OSVDRUPAL-CONTRIB-2026-090 No score
The Token Content Access module enables site administrators to provide access to content using access tokens.
The module does not sufficiently protect access token comparison in some cases. This could allow a persistent attacker to use a timing attack to guess a valid access token and bypass access restrictions for content protected by this module.
This vulnerability is mitigated by the fact that an attacker must know or discover a URL for content protected by Token Content Access, and exploiting the issue requires measuring timing differences in token comparison responses.
