AVideo through commit c91b5975d contains a cross-site request forgery vulnerability in plugin/Live/saveLive.php that lacks forbidIfNotPost and forbidIfInvalidToken protections. Attackers can craft malicious image tags to overwrite authenticated streamers' RTMP keys, passwords, and titles, hijacking live broadcasts.
AnalysisAI
Cross-site request forgery in WWBN AVideo through commit c91b5975d allows unauthenticated remote attackers to hijack authenticated streamers' live broadcasts by tricking them into loading a malicious page. The saveLive.php endpoint in the Live plugin omits both POST-method enforcement (forbidIfNotPost) and CSRF token validation (forbidIfInvalidToken), so a crafted image tag silently overwrites the victim's RTMP key, password, and stream title when loaded by a logged-in streamer. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must be an authenticated AVideo streamer with an active session at the time of the attack - the CVSS UI:P metric reflects this passive interaction requirement. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:P/VI:H) accurately characterizes the attack: no authentication is required of the attacker, complexity is low, and the integrity impact to the victim's stream session is high. … 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 referenced in GitHub Security Advisory GHSA-6jj8-2953-6frf, which should add forbidIfNotPost and forbidIfInvalidToken guards to the saveLive.php endpoint. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: restrict network access to the saveLive.php endpoint to trusted IP ranges if operationally feasible, and alert all authenticated users (streamers) to avoid clicking untrusted links while logged in and to verify stream settings before going live. …
