CVE-2026-33766: AVideo has SSRF Protection Bypass via HTTP Redirect in Image Download Endpoints

Noroxi assessment

Priority: Monitor (action score 21/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.24% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. No account or password is required. No special conditions are required; it is repeatable.
No fixed version is recorded, but the references include a patch (commit or PR) link.

Low priority for now. See the fix and affected versions sections below.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
