OpenAM 16.1.1 PKCE Abuse: Missing code_verifier in AuthzCode Grant
CVE-2026-48717 9.1 - Critical - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, AuthorizationCodeGrantTypeHandler requires a code_verifier only when the realm-wide codeVerifierEnforced setting is enabled, even when an authorization code stores a code_challenge. Because that setting is disabled by default, an attacker who intercepts a PKCE-protected authorization code can omit code_verifier and redeem the code, while an explicitly incorrect verifier is rejected. Public clients are directly affected, and confidential-client exploitation additionally requires client authentication material or another redemption context. This issue is fixed in version 16.1.1.

OpenAM 16.1.1: JWT Auth Bypass via ClientJwksResolverCache
CVE-2026-47426 7.6 - High - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the private_key_jwt client authentication path uses ClientJwksResolverCache without reliably binding a cached jwks_uri resolver and verified assertion to the expected clientID in ClientCredentialsReader. An attacker controlling any registered client with published keys, including one obtained through open dynamic registration when enabled, can authenticate as another client whose keys are exposed through jwks_uri and mint tokens in that client's name across realms in the same OpenAM process. This issue is fixed in version 16.1.1.

OpenAM 16.x GroovySandboxValueFilter Bypass: Auth Escalation to OS Cmd Execution
CVE-2026-47424 7.5 - High - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, GroovySandboxValueFilter permits an authenticated server-side script author to escape the scripting sandbox despite the default class allow and deny lists. A user such as a sub-realm RealmAdmin who can create or edit a script in an executed context can invoke operating-system commands as the OpenAM application server account, crossing the realm-scoped administration boundary and compromising the JVM and every realm it serves. This issue is fixed in version 16.1.1.

Protection Mechanism Failure

OpenAM 16.1.1 LDAP Injection via unescaped _queryId
CVE-2026-41573 7.1 - High - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, IdentityResourceV1.queryCollection() passes the _queryId parameter from /json/{realm}/users to CrestQuery with escapeQueryId disabled, bypassing protection added for CVE-2021-29156. The unescaped value reaches DJLDAPv3Repo.getFilter(), where it is concatenated into an LDAP filter, allowing an authenticated attacker to inject LDAP metacharacters for user enumeration and blind LDAP injection. This issue is fixed in version 16.1.1.

LDAP Injection

OpenAM OAuth2 Authorize endpoint XSS session theft (13.0.0-16.1.2)
CVE-2026-62280 6.1 - Medium - September 15, 2026

Open Access Management (OpenAM) is an access management solution. From 13.0.0 until 16.1.2, the OAuth2 authorize endpoint's display=wap consent page reflects request-derived values through ConsentRequiredResource and wap/authorize.ftl without HTML escaping. An attacker can induce a user with an active OpenAM session to follow a crafted authorization link and execute JavaScript in the OpenAM origin, enabling session or cookie theft, CSRF-token disclosure, and actions with the victim's privileges. At least one registered OAuth2 client is required, but the attacker does not need to control that client. This issue is fixed in version 16.1.2.

XSS

CVE-2026-45051: OpenAM <16.1.1 Deserializes AuthenticatorImpl RCE via WebAuthn
CVE-2026-45051 9.2 - Critical - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, WebAuthnAuthentication loads a serialized AuthenticatorImpl object graph from the configured userAttribute through loadAuthenticators without an ObjectInputFilter. Exploitation requires the WebAuthn flow to be reachable and an attacker to have previously written controlled data to that attribute through delegated administration, provisioning, directory access, legacy REST self-registration, or unsafe configuration. When those non-default conditions hold, the data is deserialized before assertion verification and can execute a classpath gadget in the application server process. This issue is fixed in version 16.1.1.

Marshaling, Unmarshaling

OpenAM <16.1.2 WebAuthn deserialization gadget chain bypass
CVE-2026-62263 9.2 - Critical - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.2, WebAuthnAuthentication.deserialize applies an ObjectInputFilter that allows every serialized object at depth greater than 1 and therefore constrains only an AuthenticatorImpl root object. A pre-authentication attacker can supply a userHandle whose serialized graph has a valid AuthenticatorImpl root and a nested gadget class, causing readObject or readResolve execution before the cast and assertion verification when a usable gadget is on the classpath. This bypasses the incomplete remediation for the earlier WebAuthn deserialization vulnerability. This issue is fixed in version 16.1.2.

Marshaling, Unmarshaling

OpenAM 16.1.0 OAuth2 Local Account Takeover via userPassword rewrite
CVE-2026-46623 7.4 - High - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the OAuth2 authentication module updates an existing local account with profile attributes that can include userPassword and inetUserStatus, rewriting the password to the username and reactivating disabled accounts. The missing OAuth.removeRestrictedAccountUpdateAttributes filtering permits these credential and status fields to reach the account update. With account creation enabled, repeated OAuth login causes the default ldapService chain to accept the username as both identifier and password, allowing an unauthenticated attacker to take over the local account without interacting with the identity provider. The rewrite can be denied for usernames shorter than the configured minimum password length. This issue is fixed in version 16.1.1.

Unverified Password Change

OpenAM LDAP Injection via MSISDNValidation Before 16.1.1
CVE-2026-46619 9.3 - Critical - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, MSISDNValidation in the MSISDN authentication module concatenates the request-supplied MSISDN value into an LDAP search filter without escaping, while the default empty trusted-gateway list allows all traffic. In a realm where an MSISDN module is enabled in a reachable authentication chain, an unauthenticated remote attacker can inject LDAP filter metacharacters, select an arbitrary matching user, and obtain a normal authenticated OpenAM session without a password. This issue is fixed in version 16.1.1.

LDAP Injection

OpenAM <16.1.1: OAuthTokenStore/Adapter Token ID Spoofing
CVE-2026-46498 7.6 - High - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, OAuthTokenStore reads caller-supplied token identifiers from the shared Core Token Store (CTS) without an OAuth-only namespace, and OAuthAdapter accepts a row whose BLOB claims to contain an OAuth token without binding the trusted CTS type or verifying integrity. An attacker who can place controlled JSON in CTS under a known token identifier, such as through Push Registration followed by an anonymous SNS callback in an enabled realm, can mint OAuth bearer tokens and OpenID Connect ID tokens with chosen subject, client, realm, and scope. The flaw does not by itself create an OpenAM SSO session or grant console access. This issue is fixed in version 16.1.1.

Insecure Direct Object Reference / IDOR

OpenAM <16.1.1 SNS Callback Deser Exploit for Class.forName RCE
CVE-2026-45794 7.7 - High - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the anonymous Push Notification SNS callback handled by SnsMessageResource falls back to a CTS predicate blob after a messageId expires from the in-memory dispatcher, treats top-level blob keys as Java class names for Class.forName, and deserializes attacker-controlled JSON through Jackson. A low-privileged user who starts Push Registration and obtains the messageId, shared secret, and challenge can wait for expiry, replace the persistent blob through anonymous callbacks, and trigger class loading and construction in the OpenAM JVM. The primitive can cause classpath-dependent process execution, file writes, or denial of service, although command execution was not confirmed on the tested stock classpath. This issue is fixed in version 16.1.1.

Marshaling, Unmarshaling

OpenAM <16.1 session hijack via SessionRequestHandler
CVE-2026-45048 8.5 - High - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, SessionRequestHandler in the session management endpoint does not enforce ownership or privilege checks when a low-privileged authenticated user queries session information in deployments using stateful session storage. A requester who knows a target identity identifier can retrieve another user's active session credentials, including credentials for a more privileged account, and use them to hijack that session. This issue is fixed in version 16.1.1.

Information Disclosure

OpenAM <16.1.1 FormsPostResponse XSS via OAuth/OIDC
CVE-2026-44203 8.3 - High - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the OAuth 2.0 and OpenID Connect authorization endpoint does not sufficiently encode user-supplied parameters before FormPostResponse.ftl and checkSession.ftl render them into HTML for the form_post response mode. An unauthenticated attacker can induce a user to open a crafted authorization request and execute script in the OpenAM origin. This issue is fixed in version 16.1.1.

XSS

OpenAM <16.1.1: addSessionListener allows Auth URL Injection
CVE-2026-44202 5.3 - Medium - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the /sessionservice addSessionListener operation allows an authenticated user to register an arbitrary notification URL without requiring an administrative or application client token. SessionRequestHandler passes the attacker-controlled destination to the session listener service, causing the OpenAM server to make outbound requests and potentially disclose session-related notification data to an attacker-controlled destination. This issue is fixed in version 16.1.1.

SSRF

OpenAM <=16.1.1 RCE via /authservice PLL deserialization
CVE-2026-62379 9.8 - Critical - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.2, the pre-authentication /authservice PLL endpoint accepts a CustomCallback XML element whose className value selects an arbitrary Java class for AuthXMLUtils to load and instantiate without verifying that it implements DSAMECallbackInterface. Default configurations expose the endpoint without authentication, allowing attacker-controlled class initialization and unsafe deserialization of a serialized Subject value to execute code in the server process. Enabling sunRemoteAuthSecurityEnabled does not prevent the vulnerable parsing and instantiation because its check occurs later. This issue is fixed in version 16.1.2.

Code Injection

OpenAM <=16.1.0 HttpOnly Disabled SSO Cookie & CSRF Reuse
CVE-2026-53660 7.4 - High - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the default configuration initializes the iPlanetDirectoryPro SSO cookie with HttpOnly disabled and without a protective SameSite default, and OAuth and OpenID Connect consent flows reuse that cookie through CsrfProtection as a CSRF token. When combined with same-origin cross-site scripting and a user following an attacker-controlled link, the cookie can be read and reused to steal the SSO session and complete attacker-driven consent grants. This issue is fixed in version 16.1.1.

Sensitive Cookie Without 'HttpOnly' Flag

OpenAM 16.1.1 Unauth SOAP Write to Discovery Store (before 16.1.1)
CVE-2026-45052 9.3 - Critical - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the Liberty Web Services SOAP receiver permits unauthenticated remote requests to write persistent entries through SOAPReceiver and DiscoveryService into a user's Liberty Discovery store and the shared root-realm Discovery branch. The server-side handlers bypass requester LDAP and identity ACLs, and the global path uses an internal administrative token. Deployments that consume Liberty discovery data can subsequently use manipulated service-routing or security-mechanism records. This issue is fixed in version 16.1.1.

OpenAM <16.1.1 Clustered SAML Redirect XSS (cookie-hash path)
CVE-2026-44793 7 - High - September 15, 2026

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, certain federation endpoints in a non-default clustered configuration inconsistently encode user-supplied parameters rendered into HTML in the SAML2 cluster cookie-hash redirect path. An unauthenticated attacker can induce a user to follow a crafted request and execute script in the OpenAM origin. This issue is fixed in version 16.1.1.

XSS

OpenAM <16.0.0 OIDC Claims Injection via groovy script
CVE-2025-64099 - November 12, 2025

Open Access Management (OpenAM) is an access management solution. In versions prior to 16.0.0, if the "claims_parameter_supported" parameter is activated, it is possible, thanks to the "oidc-claims-extension.groovy" script, to inject the value of one's choice into a claim contained in the id_token or in the user_info. In the request of an authorize function, a claims parameter containing a JSON file can be injected. This JSON file allows attackers to customize the claims returned by the "id_token" and "user_info" files. This allows for a very wide range of vulnerabilities depending on how clients use claims. For example, if some clients rely on an email field to identify a user, an attacker can choose the email address they want, and therefore assume any identity they choose. Version 16.0.0 fixes the issue.

Injection

OpenAM SAMLPOSTProfileServlet Signature Validation Flaw (v < 14.7.3)
CVE-2023-37471 9.8 - Critical - July 20, 2023

Open Access Management (OpenAM) is an access management solution that includes Authentication, SSO, Authorization, Federation, Entitlements and Web Services Security. OpenAM up to version 14.7.2 does not properly validate the signature of SAML responses received as part of the SAMLv1.x Single Sign-On process. Attackers can use this fact to impersonate any OpenAM user, including the administrator, by sending a specially crafted SAML response to the SAMLPOSTProfileServlet servlet. This problem has been patched in OpenAM 14.7.3-SNAPSHOT and later. User unable to upgrade should comment servlet `SAMLPOSTProfileServlet` from their pom file. See the linked GHSA for details.
