{"id":"CVE-2026-50284","state":"PUBLISHED","title":"Craft CMS: Missing peer-permission check in `AssetsController::actionDeleteFolder` allows deletion of other users' assets","description":"Craft CMS is a content management system (CMS). In versions 5.0.0-RC1 through 5.9.21 and 4.0.0-RC1 through 4.17.14, theAssetsController::actionDeleteFolder() only requires the deleteAssets:<volume-uid> permission for the target folder. It never enforces deletePeerAssets:<volume-uid>, even though Assets::deleteFoldersByIds() cascades deletion to every descendant folder and every asset inside, regardless of the uploader's assigned privileges. A low-privilege user who has been granted folder-management rights on a shared volume can therefore destroy assets uploaded by other users (peer assets), bypassing the per-asset peer-permission check that the sibling actionDeleteAsset endpoint correctly applies. This issue has been fixed in versions 4.17.15 and 5.9.22.","publishedAt":"2026-07-01T22:37:30.334Z","updatedAt":"2026-07-02T12:46:04.509Z","severity":{"score":7.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:L/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["craftcms cms"],"affected":[{"vendor":"craftcms","product":"cms","versions":[{"version":"=>= 5.0.0-RC1, < 5.9.22","status":"affected"},{"version":">= 4.0.0-RC1, < 4.17.15","status":"affected"}]}],"references":["https://github.com/craftcms/cms/security/advisories/GHSA-7h62-6v23-v8fm","https://github.com/craftcms/cms/commit/b4e08977f0c9bdf002a77f9f6d1346cd55ac0598"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/50xxx/CVE-2026-50284.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-50284","state":"PUBLISHED","datePublished":"2026-07-01T22:37:30.334Z","dateUpdated":"2026-07-02T12:46:04.509Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-04T16:26:05.985Z"},"containers":{"cna":{"title":"Craft CMS: Missing peer-permission check in `AssetsController::actionDeleteFolder` allows deletion of other users' assets","descriptions":[{"lang":"en","value":"Craft CMS is a content management system (CMS).
