{"id":"CVE-2026-41062","aliases":["GHSA-m63r-m9jh-3vc6"],"url":"https://o3.security/vulnerability/CVE-2026-41062","summary":"WWBN/AVideo has an incomplete fix for a directory traversal bypass via query string in ReceiveImage downloadURL parameters","details":"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.","published":"2026-04-21T22:57:26.304Z","modified":"2026-08-07T11:51:03.013816994Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"wwbn/avideo","fixedVersion":null}],"fix":{"url":"https://github.com/WWBN/AVideo/commit/2375eb5e0a6d3cbcfb05377657d0820a7d470b1d","label":"WWBN/AVideo@2375eb5"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41062.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-f4f9-627c-jh33"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-m63r-m9jh-3vc6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41062"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/2375eb5e0a6d3cbcfb05377657d0820a7d470b1d"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/bd11c16ec894698e54e2cdae25026c61ad1ed441"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:51:03.013816994Z"}}
