{"id":"DRUPAL-CONTRIB-2026-090","details":"The Token Content Access module enables site administrators to provide access to content using access tokens.\n\nThe 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.\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.","aliases":["CVE-2026-18259"],"modified":"2026-09-10T03:46:16.802424447Z","published":"2026-07-29T17:08:33Z","references":[{"type":"WEB","url":"https://www.drupal.org/sa-contrib-2026-090"}],"affected":[{"package":{"name":"drupal/tca","ecosystem":"Packagist:https://packages.drupal.org/8","purl":"pkg:composer/drupal/tca?repository_url=https:%2F%2Fpackages.drupal.org%2F8"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.2"}],"database_specific":{"constraint":"\u003c3.1.2"}}],"database_specific":{"affected_versions":"\u003c3.1.2","source":"https://github.com/DrupalSecurityTeam/drupal-advisory-database/blob/main/advisories/tca/DRUPAL-CONTRIB-2026-090.json"}}],"schema_version":"1.9.0","credits":[{"name":"Robin  (robincs)","contact":["https://www.drupal.org/u/robincs"]}]}
