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.","severity":"unknown","score":null,"published":"2026-07-29T17:08:33.000Z","modified":"2026-09-10T03:46:16.802Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist:https://packages.drupal.org/8","name":"drupal/tca","sources":[{"name":"OSV · DRUPAL-CONTRIB-2026-090","url":"https://osv.dev/vulnerability/DRUPAL-CONTRIB-2026-090"}],"ranges":[{"events":[{"introduced":"0"},{"fixed":"3.1.2"}],"type":"ECOSYSTEM","database_specific":{"constraint":"<3.1.2"}}],"versions":[],"fixed":["3.1.2"]}],"sourceAffected":[],"references":["https://www.drupal.org/sa-contrib-2026-090"],"sources":[{"name":"OSV","id":"DRUPAL-CONTRIB-2026-090","modified":"2026-09-10T03:46:16.802424447Z","url":"https://osv.dev/vulnerability/DRUPAL-CONTRIB-2026-090"}],"assessments":[],"products":[],"remediation":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T18:10:32.025Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
