{"id":"CVE-2026-43879","summary":"WWBN AVideo: Blind SSRF in YPTWallet Donation Webhook via Missing isSSRFSafeURL() Check and CURLOPT_FOLLOWLOCATION Redirect Bypass","details":"WWBN AVideo is an open source video platform. In versions up to and including 29.0, an authenticated user can configure their own donation-notification webhook URL to point at internal/loopback/metadata hosts (e.g. http://127.0.0.1:8080/..., http://169.254.169.254/latest/..., RFC1918 addresses). When any other user (including a second account owned by the same attacker) donates even a trivial amount via plugin/CustomizeUser/donate.json.php, the AVideo server issues a curl POST to the attacker-supplied URL, resulting in a blind SSRF. The handler uses only isValidURL() (which is a format check) and does not call the codebase's own isSSRFSafeURL() helper. Additionally, CURLOPT_FOLLOWLOCATION is enabled with no per-hop revalidation, so even if the stored URL were validated, an HTTP 307 from an attacker-controlled host could redirect the POST to internal targets. Commit aaacd48f29f1ff71d1eb5fc81d37605f593cefa9 contains an updated fix.","aliases":["GHSA-wp38-whx3-xffh"],"modified":"2026-07-08T08:13:27.807279885Z","published":"2026-05-11T20:36:34.210Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43879.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43879.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-wp38-whx3-xffh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43879"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/aaacd48f29f1ff71d1eb5fc81d37605f593cefa9"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"fixed":"aaacd48f29f1ff71d1eb5fc81d37605f593cefa9"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"last_affected":"29.0"}]}}],"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-2026-43879.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"}]}
