{"id":"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.","aliases":["GHSA-m63r-m9jh-3vc6"],"modified":"2026-08-12T03:51:41.878753365Z","published":"2026-04-21T22:57:26.304Z","related":["GHSA-f4f9-627c-jh33","GHSA-m63r-m9jh-3vc6"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41062.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"fixed":"2375eb5e0a6d3cbcfb05377657d0820a7d470b1d"},{"fixed":"bd11c16ec894698e54e2cdae25026c61ad1ed441"}],"database_specific":{"cpe":"cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"29.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["29.0","26.0","25.0","24.0","22.0","21.0","18.0","14.3.1","14.3","12.4","11.6","11.5","11.1.1","11.1","11","10.8","8.9.1","8.9","8.7","8.6","8.5","8.1","7.8","7.7","7.6","7.4","7.3","7.2","4.0","3.4","2.7","2.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41062.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
