WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a server-side request forgery vulnerability in the _json_decode function that fetches remote URLs and local file paths without SSRF validation. Unauthenticated attackers can POST file paths or HTTP URLs to login.json.php to read local files or access internal services, with results parsed as login credentials.
AnalysisAI
Server-side request forgery in WWBN AVideo's login endpoint enables unauthenticated remote attackers to read arbitrary local files or probe internal services by supplying crafted file paths or HTTP URLs to login.json.php. The vulnerability resides in the _json_decode function, which fetches attacker-supplied URLs and local paths without SSRF validation; the fetched content is then parsed as login credentials, creating an unusual secondary attack surface for potential authentication bypass against internal services that return predictable responses. …

Vulnerability AssessmentAI
| Exploitation | No special conditions are required beyond network access to the login.json.php endpoint - exploitation is unauthenticated (PR:N) and requires no user interaction (UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 reflects a medium-severity assessment with network-accessible unauthenticated exploitation (AV:N/AC:L/PR:N/UI:N) but limited confidentiality and integrity impact (VC:L/VI:L/VA:N), consistent with an SSRF that leaks file content rather than achieving direct code execution. … 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 | Upgrade to an AVideo release incorporating the fix committed after c3edcc274c389816d434acadac07ee78eaf330c1; consult the GitHub security advisory GHSA-wqwf-wmvx-53jh for the exact patched commit or tagged release. … Detailed patch versions, workarounds, and compensating controls in full report. |
