Grafana 9.2.4,8.5.15: User Disclosure via /api/user/password/sent-reset-email
CVE-2022-39307 Published on November 9, 2022
Grafana subject to Exposure of Sensitive Information resulting in User enumeration via forget password
Grafana is an open-source platform for monitoring and observability. When using the forget password on the login page, a POST request is made to the `/api/user/password/sent-reset-email` URL. When the username or email does not exist, a JSON response contains a user not found message. This leaks information to unauthenticated users and introduces a security risk. This issue has been patched in 9.2.4 and backported to 8.5.15. There are no known workarounds.
