An attacker can bypass SSRF protection by redirecting from a public URL to an internal target.
MEDIUM 5.3EPSS 0.23%
Does this matter?
Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.
Description
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.
