The endpoint validates only the Category::canCreateCategory() capability and a CSRF nonce before passing the attacker-supplied $_REQUEST['id'] to Category::deleteAssets(), which recursively removes {systemRootPath}videos/categories/assets/{id}/. It omits the Category::userCanEditCategory() ownership check enforced by the sibling Category::delete(). On installations where the non-default usersCanCreateNewCategories setting is enabled, an authenticated non-admin user with the canUpload capability can send a POST request with an arbitrary category ID and recursively delete any category's on-disk asset directory (icons/images). Category records and videos are not deleted. As of the advisory publication no patched version was available."}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Authorization Bypass Through User-Controlled Key","cweId":"CWE-639","type":"CWE"}]}],"affected":[{"vendor":"WWBN","product":"AVideo","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","versionType":"custom","lessThanOrEqual":"29.0"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*","versionEndIncluding":"29.0"}]}]}],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"LOW","userInteraction":"NONE","vulnConfidentialityImpact":"NONE","vulnIntegrityImpact":"LOW","vulnAvailabilityImpact":"LOW","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","baseScore":5.3,"baseSeverity":"MEDIUM"}},{"format":"CVSS","cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"LOW","baseScore":5.4,"baseSeverity":"MEDIUM"}}],"references":[{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-gf2v-r8wx-ghqj","tags":["vendor-advisory"],"name":"GitHub Security Advisory (GHSA-gf2v-r8wx-ghqj)"},{"name":"VulnCheck Advisory: AVideo through 29.0 Cross-User Category Asset Deletion via Missing Ownership Check","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/avideo-through-29.0-cross-user-category-asset-deletion-via-missing-ownership-check"}],"credits":[{"lang":"en","value":"manus-use","type":"reporter"}],"x_generator":{"engine":"vulncheck-endgame"}},"adp":[{"references":[{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-gf2v-r8wx-ghqj","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-15T16:16:21.067580Z","id":"CVE-2026-89257","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-15T16:16:54.171Z"}}]}}
