{"identifier":"CVE-2026-40926","cve":{"id":"CVE-2026-40926","description":"WWBN AVideo is an open source video platform. In versions 29.0 and prior, three admin-only JSON endpoints — `objects/categoryAddNew.json.php`, `objects/categoryDelete.json.php`, and `objects/pluginRunUpdateScript.json.php` — enforce only a role check (`Category::canCreateCategory()` / `User::isAdmin()`) and perform state-changing actions against the database without calling `isGlobalTokenValid()` or `forbidIfIsUntrustedRequest()`. Peer endpoints in the same directory (`pluginSwitch.json.php`, `pluginRunDatabaseScript.json.php`) do enforce the CSRF token, so the missing checks are an omission rather than a design choice. An attacker who lures a logged-in admin to a malicious page can create, update, or delete categories and force execution of any installed plugin's `updateScript()` method in the admin's session. Commit ee5615153c40628ab3ec6fe04962d1f92e67d3e2 contains a fix.","published":"2026-04-21T23:16:20.163000+00:00","modified":"2026-10-26T22:10:00.163000+00:00","status":"Analyzed","score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:L","cvss_version":"3.1","affected":[{"criteria":"cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*","versionStartIncluding":"","versionStartExcluding":"","versionEndIncluding":"29.0","versionEndExcluding":""}],"weaknesses":["CWE-352"],"references":[{"url":"https://github.com/WWBN/AVideo/commit/ee5615153c40628ab3ec6fe04962d1f92e67d3e2","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-ffw8-fwxp-h64w","source":"security-advisories@github.com","tags":["Exploit","Mitigation","Vendor Advisory"]},{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-ffw8-fwxp-h64w","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Mitigation","Vendor Advisory"]}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:L","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"LOW"},"exploitabilityScore":2.8,"impactScore":4.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-04-22T13:57:39.434922Z","id":"CVE-2026-40926","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*","versionEndIncluding":"29.0","matchCriteriaId":"AC38CA07-71C1-4C86-B84A-83CF96367CBA"}]}]}],"source":"nvd","retrieved_at":"2026-10-28T10:19:29.199063+00:00","exploited":false,"kev_stale":false,"products":["wwbn / avideo"],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00166,"percentile":0.05804,"date":"2026-10-27","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/WWBN/AVideo/commit/ee5615153c40628ab3ec6fe04962d1f92e67d3e2","investigate_url":"https://investigate.aeglixmind.com/#github.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-40926","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-40926","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-40926","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
