As a result, a user with \"edit field collections\" but without edit/update access to the host entity (for example a node they cannot edit) could edit or delete field collection items attached to that entity, bypassing the intended entity/node access restrictions. The fix requires access to the parent entity in addition to the field collection permission.\n\n\n\nThis issue affects Field Collection for Drupal 7: version 7.x-1.0 up to and including 7.x-1.2.","epss":{"date":"2026-11-06","percentile":0.13684,"score":0.00228},"exploits":[],"kev":null,"metrics":[{"score":5.3,"severity":"medium","source":"CNA: drupal","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},{"score":5.3,"severity":"medium","source":"NVD: mlhess@drupal.org","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"}],"modifiedAt":1793980561526,"publishedAt":1793404589862,"references":[{"source":"CNA: drupal","tags":["third-party-advisory"],"url":"https://www.herodevs.com/vulnerability-directory/cve-2026-77152"},{"source":"CNA: drupal","tags":["third-party-advisory"],"url":"https://d7es.tag1.com/security-advisories?field_project_target_id=96"},{"source":"mlhess@drupal.org","tags":[],"url":"https://d7es.tag1.com/security-advisories?field_project_target_id=96"},{"source":"mlhess@drupal.org","tags":[],"url":"https://www.herodevs.com/vulnerability-directory/cve-2026-77152"}],"remediation":[],"revision":"956ff6d7030ea18ae4ba2a1c580b5517160cdfeb7912fec974a67e958f22a6bd","sources":[{"modifiedAt":1793980561526,"name":"CNA: drupal","retrievedAt":1793981801228,"url":"https://www.cve.org/CVERecord?id=CVE-2026-77152"},{"modifiedAt":1793636332027,"name":"NVD","retrievedAt":1793643478134,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77152"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793981814626,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-77152"}],"ssvc":{"assessedAt":1793980541577,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Field Collection for Drupal 7 access bypass via missing parent entity access check","updatedAt":1793981814626}
