In AVideo through 29.0, the API get_api_video endpoint contains a broken access control vulnerability in the clean_title branch that returns user-group-restricted videos with owner PII to anonymous callers. Attackers can query videos by their public slug to bypass group restrictions and retrieve sensitive user fields including email, phone, address, birth date, and administrator status.
AnalysisAI
Unauthenticated information disclosure in AVideo through 29.0 lets any anonymous caller pull owner PII - email address, phone number, physical address, birth date, and administrator status - alongside metadata for videos that are supposed to be visible only to specific user groups. The defect lives in the clean_title branch of the get_api_video API endpoint, which performs no group-membership check when a video is requested by its public slug, so an attacker who knows or enumerates a slug bypasses the access control entirely (CWE-639, tagged Authentication Bypass). …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No authentication, user interaction, or special client configuration is required: an anonymous caller reaches the API get_api_video endpoint and triggers the clean_title branch by querying a video via its public slug. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are largely consistent and point to a genuine, easy-to-exploit information-disclosure flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch version is identified in the available data, so the primary action is to check the upstream advisory GHSA-w59h-5r8w-686r (and the VulnCheck advisory) for a patched release and upgrade beyond 29.0 as soon as one is published; do not assume a specific fix version until the vendor states it. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, restrict external network access to the AVideo get_api_video API endpoint, specifically requests that use the clean_title parameter or public video slugs, using WAF, reverse-proxy, or firewall rules; review AVideo access logs for anonymous requests to the API and identify any exposed slugs; and notify the security team and platform owners. …
