6.5 MEDIUM

Network-reachable, no privileges or user interaction; integrity and availability both low as the flaw enables brute force and email flooding but does not directly exfiltrate or destroy data.

DescriptionCVE.org

WWBN AVideo contains an unauthenticated credential submission vulnerability in plugin/Live/api/preauthorize.json.php that accepts credentials over GET without rate limiting. Attackers can submit correct credentials repeatedly to trigger uncapped two-factor confirmation emails and perform sustained password guessing attacks against user accounts.

AnalysisAI

WWBN AVideo's Live plugin exposes an unauthenticated endpoint at plugin/Live/api/preauthorize.json.php that accepts credentials via HTTP GET with no rate limiting, enabling two distinct abuse vectors: sustained brute-force password guessing against any user account and uncapped triggering of two-factor authentication confirmation emails. All versions of AVideo are affected per CPE data, and exploitation requires no privileges or user interaction. …

Vulnerability AssessmentAI

Exploitation The WWBN AVideo Live plugin must be installed and active - this is not a core AVideo vulnerability but is specific to the Live plugin component. … 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:N/VC:N/VI:L/VA:L) yields a score of 6.9 (Medium), reflecting the low-complexity remote unauthenticated nature of the attack but conservatively rating impact as low on both integrity and availability. … 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 The primary fix is to apply the vendor-released patch documented in the GitHub security advisory at https://github.com/WWBN/AVideo/security/advisories/GHSA-gxxj-32wm-g48f - an exact fixed version number is not independently confirmed from available data, so operators should verify the current patched release tag directly. … Detailed patch versions, workarounds, and compensating controls in full report.
