AnalysisAIv1 – Sep 15, 2026

AVideo through 29.0 is affected by a blind server-side request forgery (SSRF) in the getHeaderContentTypeFromURL function, which performs get_headers() calls on URL values that are only checked for format rather than destination. An authenticated user holding the canUpload permission can persist an attacker-chosen URL as a video link; the vulnerable lookup then fires on every render of that video's watch page, letting the attacker probe internal hosts and infer results through content-type differences and response timing. No public exploit code or CISA KEV entry is associated with this CVE at time of analysis, and no EPSS score was supplied in the input, so real-world exploitation activity remains unconfirmed.

DescriptionCVE.org

AVideo through 29.0 contains a blind server-side request forgery vulnerability in the getHeaderContentTypeFromURL function that issues get_headers() calls guarded only by format validation. Authenticated users with canUpload permission can store attacker-chosen URLs as video links, triggering vulnerable function execution on every video watch page render to probe internal hosts using content-type oracles and timing-based detection.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
