Server-Side Request Forgery in AVideo EPG Parser

Publication date: 2026-09-03

Last updated on: 2026-09-03

Assigner: VulnCheck

Description
AVideo through commit c91b5975d contains a server-side request forgery vulnerability in the EPG parser that allows authenticated uploaders to fetch arbitrary internal URLs. An attacker can supply an internal URL via the epg_link parameter during video upload, which is validated only for syntax and later fetched server-side during EPG generation without SSRF protection checks.

Executive Summary

AVideo has a server-side request forgery (SSRF) vulnerability in its EPG parser. Authenticated users with upload privileges can exploit this by providing an internal URL via the epg_link parameter during video upload. The server fetches this URL during EPG generation without proper SSRF protection, allowing access to internal resources.

Detection Guidance

To detect this SSRF vulnerability in AVideo, monitor network traffic for outbound requests from the server originating from the EPG parser during video uploads. Check logs for unusual URLs in the epg_link parameter. Use tools like tcpdump or Wireshark to capture server-side requests to internal or external URLs.

Impact Analysis

An attacker could access internal services, steal sensitive data, or perform unauthorized actions on internal systems. This includes potential exposure of internal network structure, credentials, or other confidential information.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, violating GDPR's data protection principles or HIPAA's security requirements. Organizations may face compliance violations, legal penalties, and reputational damage if exploited.

Mitigation Strategies

Immediately update AVideo to the latest commit or patch that addresses the SSRF issue. Implement strict input validation for the epg_link parameter, blocking internal IP ranges and non-HTTP/HTTPS URLs. Disable EPG parsing for untrusted users until patched. Monitor server logs for suspicious activity.
