{"identifier":"CVE-2026-34364","cve":{"id":"CVE-2026-34364","description":"WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `categories.json.php` endpoint, which serves the category listing API, fails to enforce user group-based access controls on categories. In the default request path (no `?user=` parameter), user group filtering is entirely skipped, exposing all non-private categories including those restricted to specific user groups. When the `?user=` parameter is supplied, a type confusion bug causes the filter to use the admin user's (user_id=1) group memberships instead of the current user's, rendering the filter ineffective. Commit 6e8a673eed07be5628d0b60fbfabd171f3ce74c9 contains a fix.","published":"2026-03-27T18:16:05.570000+00:00","modified":"2026-10-26T21:10:00.170000+00:00","status":"Analyzed","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","cvss_version":"3.1","affected":[{"criteria":"cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*","versionStartIncluding":"","versionStartExcluding":"","versionEndIncluding":"26.0","versionEndExcluding":""}],"weaknesses":["CWE-863"],"references":[{"url":"https://github.com/WWBN/AVideo/commit/6e8a673eed07be5628d0b60fbfabd171f3ce74c9","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-73gr-r64q-7jh4","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-73gr-r64q-7jh4","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","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:N/S:U/C:L/I:N/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":1.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-03-27T18:31:28.325247Z","id":"CVE-2026-34364","options":[{"exploitation":"poc"},{"automatable":"yes"},{"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":"26.0","matchCriteriaId":"774C24F1-9D26-484F-B931-1DA107C8F588"}]}]}],"source":"nvd","retrieved_at":"2026-10-28T10:18:20.578951+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":0.00332,"percentile":0.26361,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/WWBN/AVideo/commit/6e8a673eed07be5628d0b60fbfabd171f3ce74c9","investigate_url":"https://investigate.aeglixmind.com/#github.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-34364","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-34364","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-34364","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
