WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a cross-site request forgery vulnerability in deleteHistory.json.php and finishAll.json.php that allows unauthenticated attackers to mutate live history by making GET requests without CSRF token validation. Attackers can craft malicious pages that trigger administrator browsers to delete all live transmission history or mark streams as finished when an admin visits the attacker-controlled site.

AnalysisAI
Cross-site request forgery in WWBN AVideo through commit c3edcc274c allows unauthenticated remote attackers to manipulate live streaming state by inducing administrative users to visit attacker-controlled pages. The affected endpoints - deleteHistory.json.php and finishAll.json.php - accept state-changing GET requests without CSRF token validation, meaning a simple embedded image or link is sufficient to trigger destructive operations. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target user holds an active authenticated administrator session on the AVideo instance at the time of the attack, and that the administrator's browser loads content from an attacker-controlled origin (e.g., via a phishing link or compromised third-party page). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 7.1 (AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:H/VA:L) accurately reflects the attack profile: low complexity, no attacker privileges required, but a critical dependency on an authenticated administrator visiting an attacker-controlled site. … 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 | Apply the fix documented in GitHub Security Advisory GHSA-gmx5-mhqr-h7rj (https://github.com/WWBN/AVideo/security/advisories/GHSA-gmx5-mhqr-h7rj); the upstream fix is available per the advisory, though the exact patched release tag was not independently confirmed from the provided data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all WWBN AVideo instances and restrict administrative console access to internal networks or require VPN + multi-factor authentication. …
