CVE-2026-8462 openmeter CVE debrief

Who should care

Defenders and security teams responsible for OpenMeter OpenMeter deployments, especially those using versions prior to v1.0.0-beta.228, should assess exposure and potential impact.

Why it matters

CVE-2026-8462 is a SQL injection vulnerability in OpenMeter OpenMeter before v1.0.0-beta.228. Defenders should prioritize verifying exposure, assessing potential impact, and taking remediation actions to prevent potential access or modification of metering event data and denial of service.

• Potential access to sensitive metering event data
• Potential modification of metering event data
• Potential denial of service via crafted JSONPath values
• Verification of OpenMeter OpenMeter version and exposure

Technical summary

The SQL injection vulnerability in OpenMeter OpenMeter before v1.0.0-beta.228 allows remote unauthenticated attackers to access or modify metering event data and potentially cause denial of service via crafted user-controlled JSONPath values submitted to the meters API. This vulnerability is due to inadequate input validation and sanitization of user-controlled JSONPath values. Defenders should prioritize verifying exposure and assessing potential impact, especially in environments using OpenMeter OpenMeter versions prior to v1.0.0-beta.228.

Defensive priority

Defenders should prioritize verifying exposure and assessing potential impact, especially in environments using OpenMeter OpenMeter versions prior to v1.0.0-beta.228.

Recommended defensive actions

• Verify OpenMeter OpenMeter version and update to v1.0.0-beta.228 or later if necessary
• Restrict access to the meters API
• Monitor for suspicious activity and potential denial of service
• Review and validate user-controlled JSONPath values
• Perform a thorough review of OpenMeter OpenMeter deployments to identify potential exposure
• Implement compensating controls for exposed systems while remediation is scheduled and verified
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
