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.\n\nThis 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.","status":"published","published":"2026-07-29T17:08:33Z","modified":"2026-09-10T03:46:16.802424447Z","updated_at":"2026-11-02T15:46:13.900249Z"}]}}
