WWBN AVideo is an open source video platform. In versions up to and including 26.0, isSSRFSafeURL() validates URLs against private/reserved IP ranges before fetching, but url_get_contents() follows HTTP redirects without re-validating the redirect target. An attacker can bypass SSRF protection by redirecting from a public URL to an internal target. Commit 8b7e9dad359d5fac69e0cbbb370250e0b284bc12 contains a patch.

MEDIUMNVD 6.56.5
EchelonGraph scoreLOW confidence
This medium-severity CVE scores 6.5 under NVD CVSS v3. EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
