CVE-2026-97363 Monta CVE debrief

Who should care

Defenders responsible for WebSocket API security, particularly those in ICS environments, should assess potential exposure and prioritize verifying rate limiting on authentication requests.

Why it matters

CVE-2026-97363 is a high-severity vulnerability in the WebSocket API that lacks rate limiting on authentication requests, potentially allowing denial-of-service or brute-force attacks. Defenders in ICS environments should prioritize verifying rate limiting and assessing potential exposure.

• Potential denial-of-service attacks
• Potential brute-force attacks to gain unauthorized access
• Need to verify rate limiting on WebSocket API authentication requests
• Possible impact on ICS environments

Technical summary

The WebSocket Application Programming Interface lacks restrictions on the number of authentication requests, potentially allowing denial-of-service attacks or brute-force attacks to gain unauthorized access. This vulnerability affects WebSocket API implementations that do not enforce rate limiting on authentication requests. Defenders should prioritize verifying the presence of rate limiting on WebSocket API authentication requests and assessing potential exposure to denial-of-service or brute-force attacks. The lack of rate limiting could allow an attacker to

Defensive priority

Defenders should prioritize verifying the presence of rate limiting on WebSocket API authentication requests and assessing potential exposure to denial-of-service or brute-force attacks.

Recommended defensive actions

• Verify rate limiting on WebSocket API authentication requests
• Assess potential exposure to denial-of-service or brute-force attacks
• Implement rate limiting on WebSocket API authentication requests if not already present
