CVE-2026-64626

AVideo Encoder downloadURL SSRF via unpinned retry fallback

State: Published
Severity: 5.3 Medium
Published: Jul 20, 2026
Updated: Jul 22, 2026
Reserved: Jul 20, 2026

Description

AVideo versions from commit 0dbadbca through latest master contain a server-side request forgery vulnerability in the encoder download-by-URL flow due to an unpinned retry fallback that bypasses DNS pinning validation. An authenticated attacker can supply a downloadURL that redirects to an internal address, causing the unpinned retry to follow the redirect and reach internal targets for blind SSRF attacks.
