CVE-2026-76240 eidetic-labs CVE debrief

Who should care

Defenders and developers using stigmem-node 0.9.0a1 should assess exposure and prioritize patching or mitigating this vulnerability to prevent potential SQL injection attacks. This includes verifying schema name validation and quoting in stigmem-node configurations, assessing exposure of stigmem-node 0.9.0a1 deployments to potential SQL injection attacks, and prioritizing patching or mitigating this vulnerability to prevent potential SQL injection attacks.

Why it matters

CVE-2026-76240 is a high-severity vulnerability in stigmem-node 0.9.0a1 that allows for potential SQL injection attacks due to the interpolation of Postgres backend schema identifiers into SQL strings without defensive quoting. Defenders and developers using stigmem-node 0.9.0a1 should assess exposure and prioritize patching or mitigating this vulnerability to prevent potential SQL injection attacks.

• Verify schema name validation and quoting in stigmem-node configurations
• Assess exposure of stigmem-node 0.9.0a1 deployments to potential SQL injection attacks
• Prioritize patching or mitigating this vulnerability to prevent potential SQL injection attacks
• Monitor for potential SQL injection attacks on stigmem-node 0.9.0a1 deployments

Technical summary

The stigmem-node 0.9.0a1 library interpolates Postgres backend schema identifiers into SQL strings without defensive quoting, allowing for potential SQL injection attacks if a schema name were derived from tenant, request, or user input. The vulnerability has a CVSS score of 7.5 and is classified as HIGH severity. The vulnerability is operator-controlled and could be exploited if a schema name were derived from tenant, request, or user input. A fix is available in version 0.9.0a2, which adds identifier quoting and validation. As a workaround, only configure schema names from trusted deployment configuration.

Defensive priority

Defenders should prioritize patching or mitigating this vulnerability to prevent potential SQL injection attacks.

Recommended defensive actions

• Patch stigmem-node to version 0.9.0a2 or later
• Configure schema names from trusted deployment configuration
• Monitor for potential SQL injection attacks
• Verify schema name validation and quoting in stigmem-node configurations
• Assess exposure of stigmem-node 0.9.0a1 deployments to potential SQL injection attacks
• Prioritize patching or mitigating this vulnerability to prevent potential SQL injection attacks
• Review compensating controls for exposed systems while remediation is scheduled and verified
