CVE-2026-97212 Monta CVE debrief

Who should care

Defenders responsible for WebSocket backend security, authentication, and session management should assess exposure and prioritize verification of session identifier uniqueness. This includes operators, platform administrators, vulnerability management teams, and security teams who need to review compensating controls for exposed systems and implement additional authentication and session management controls.

Why it matters

CVE-2026-97212 is a medium-severity vulnerability in the WebSocket backend that allows predictable session identifiers, potentially enabling unauthorized authentication or denial-of-service conditions. Defenders should prioritize verifying session identifier uniqueness and assessing exposure to these potential threats.

• Potential unauthorized authentication as other users
• Possible denial-of-service condition by overwhelming the backend with valid session requests
• Need to verify session identifier uniqueness and randomness
• Importance of implementing additional authentication and session management controls

Technical summary

The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier, resulting in predictable session identifiers. This vulnerability may allow unauthorized users to authenticate as other users or enable a malicious actor to cause a denial-of-service condition by overwhelming the backend with valid session requests. Affected product deployments should be verified for exposure, and defenders should prioritize verifying session identifier uniqueness and assessing exposure to potential unauthorized authentication or denial-of-service conditions.

Defensive priority

Defenders should prioritize verifying session identifier uniqueness and assessing exposure to potential unauthorized authentication or denial-of-service conditions.

Recommended defensive actions

• Verify session identifier uniqueness and randomness
• Assess exposure to potential unauthorized authentication or denial-of-service conditions
• Implement additional authentication and session management controls
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• 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
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, but additional information on affected versions, exploitation, and remediation is limited. The source corpus provides some context, but further verification is needed to confirm affected scope, severity, and vendor guidance. Defenders should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
