{"id":"CVE-2026-41062","state":"PUBLISHED","title":"WWBN/AVideo has an incomplete fix for a directory traversal bypass via query string in ReceiveImage downloadURL parameters","description":"WWBN AVideo is an open source video platform. In versions 29.0 and below, the directory traversal fix introduced in commit 2375eb5e0 for `objects/aVideoEncoderReceiveImage.json.php` only checks the URL path component (via `parse_url($url, PHP_URL_PATH)`) for `..` sequences. However, the downstream function `try_get_contents_from_local()` in `objects/functionsFile.php` uses `explode('/videos/', $url)` on the **full URL string** including the query string. An attacker can place the `/videos/../../` traversal payload in the query string to bypass the security check and read arbitrary files from the server filesystem. Commit bd11c16ec894698e54e2cdae25026c61ad1ed441 contains an updated fix.","publishedAt":"2026-04-21T22:57:26.304Z","updatedAt":"2026-04-22T17:57:23.136Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["WWBN AVideo"],"affected":[{"vendor":"WWBN","product":"AVideo","versions":[{"version":"<= 29.0","status":"affected"}]}],"references":["https://github.com/WWBN/AVideo/security/advisories/GHSA-m63r-m9jh-3vc6","https://github.com/WWBN/AVideo/security/advisories/GHSA-f4f9-627c-jh33","https://github.com/WWBN/AVideo/commit/2375eb5e0a6d3cbcfb05377657d0820a7d470b1d","https://github.com/WWBN/AVideo/commit/bd11c16ec894698e54e2cdae25026c61ad1ed441"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/41xxx/CVE-2026-41062.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-41062","state":"PUBLISHED","datePublished":"2026-04-21T22:57:26.304Z","dateUpdated":"2026-04-22T17:57:23.136Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-16T16:43:03.173Z"},"containers":{"cna":{"title":"WWBN/AVideo has an incomplete fix for a directory traversal bypass via query string in ReceiveImage downloadURL parameters","descriptions":[{"lang":"en","value":"WWBN AVideo is an open source video platform.
