AVideo through commit 9c39d8c8 contains a cross-site request forgery vulnerability in channelToGallery.json.php that allows attackers to modify site-wide Gallery configuration by performing unauthorized writes to plugin data. Attackers can craft a cross-site GET request carrying an administrator's session cookie to promote arbitrary channels to the front page or delete curated sections without token validation.
AnalysisAI
Cross-site request forgery in AVideo through commit 9c39d8c8 enables unauthenticated remote attackers to modify site-wide Gallery plugin configuration by exploiting the absence of CSRF token validation in channelToGallery.json.php. Any administrator who visits a crafted page while holding an active session can be silently coerced into promoting arbitrary channels to the front page or deleting curated gallery sections. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a currently authenticated AVideo administrator visit an attacker-controlled web page or load attacker-controlled content in their browser while holding an active admin session cookie - this is the UI:P (passive user interaction) condition encoded in the CVSS 4.0 vector. … 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/VC:N/VI:L/VA:L scores 5.3 (Medium), which accurately reflects the bounded real-world impact: exploitation is network-reachable and low-complexity but requires an administrator to interact with attacker-controlled content, and the resulting damage is limited to gallery configuration rather than code execution or data exfiltration. … 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 | Update AVideo to a commit or release beyond 9c39d8c8 as described in the vendor security advisory at https://github.com/WWBN/AVideo/security/advisories/GHSA-8qq4-h7xj-p2c4 and the VulnCheck advisory at https://www.vulncheck.com/advisories/avideo-channeltogallery-json-php-cross-site-request-forgery. … Detailed patch versions, workarounds, and compensating controls in full report. |
