CVE-2026-89248 WWBN CVE debrief

Who should care

AVideo users with the WebRTC plugin installed should assess their exposure and take defensive actions. This includes reviewing and restricting access to the affected endpoint, verifying plugin configuration, and monitoring for suspicious activity. Security teams should prioritize this vulnerability due to the potential for information disclosure and possible use in further attacks or reconnaissance.

Why it matters

The AVideo WebRTC plugin vulnerability allows unauthenticated access to sensitive information, posing a medium risk to users. Defenders should review and restrict access to the affected endpoint, verify plugin configuration, and monitor for suspicious activity.

• Potential information disclosure of sensitive configuration and log data
• Possible use in further attacks or reconnaissance
• Requires verification of WebRTC plugin configuration and access controls
• May impact systems using the WebRTC plugin for video streaming or communication

Technical summary

The AVideo WebRTC plugin has an unauthenticated information disclosure vulnerability. The /plugin/WebRTC/status.json.php endpoint does not perform authentication or authorization checks, allowing remote users to obtain sensitive information, including the absolute filesystem path of the WebRTC2RTMP helper binary, the configured WebRTC port, and log file contents. This issue allows unauthorized access to potentially sensitive configuration and log data, which could be used to inform further attacks or reconnaissance.

Defensive priority

Medium priority for WebRTC plugin users

Recommended defensive actions

• Review and restrict access to /plugin/WebRTC/status.json.php
• Verify WebRTC plugin configuration and remove if unnecessary
• Monitor for suspicious requests to /plugin/WebRTC/status.json.php
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record and NVD entry provide details on the vulnerability. However, the vendor and affected versions are not specified. The WebRTC plugin's unauthenticated endpoint could potentially expose sensitive information, including file paths and log contents. Defenders should verify the presence of the WebRTC plugin, review access controls, and monitor for suspicious requests to /plugin/WebRTC/status.json.php.
