Title

AVideo Encoder downloadURL SSRF via unpinned retry fallback

Summary

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.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
