Token Content Access - Moderately critical - Access bypass - SA-CONTRIB-2026-090
Observable Timing Discrepancy vulnerability in Drupal Token Content Access allows Brute Force. This issue affects Token Content Access versions: from 0.0.0 to 3.1.2.
Vulnerability Analysis
CVE-2026-18259 can be exploited with network access, and does not require authorization privileges or user interaction. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have a high impact on confidentiality, with no impact on integrity and availability.
Weakness Type
Observable Timing Discrepancy
Two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not. In security-relevant contexts, even small variations in timing can be exploited by attackers to indirectly infer certain details about the product's internal operations. For example, in some cryptographic algorithms, attackers can use timing differences to infer certain properties about a private key, making the key easier to guess. Timing discrepancies effectively form a timing side channel.
Affected Versions
Drupal Token Content Access:- Version 0.0.0 and below 3.1.2 is affected.
