Authenticated SSRF via unchecked redirects and DNS rebinding
Published May 11, 2026 · Updated May 11, 2026
SSRF in AVideo 29.0 and earlier allows remote authenticated users to read internal HTTP resources through attacker-controlled URLs. The AI callback and EPG parser check only the initial URL before bare file_get_contents() calls follow redirects, while other callers discard the resolved IP and permit DNS rebinding. An authenticated workflow is required; successful requests can expose cloud metadata, IAM credentials, or responses from internal services without altering data or interrupting service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
