CVE-2026-76240: stigmem Postgres SQL Injection via Schema Identifier

• Severity: high (CVSS 7.5 v4.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-08-19 · updated 2026-09-11
• Weakness: CWE-89

Description

stigmem-node 0.9.0a1 interpolates Postgres backend schema identifiers into SQL strings without defensive quoting. In the affected code path the schema value is operator-controlled, but the unsafe pattern could allow SQL injection if a schema name were derived from tenant, request, or user input. Fixed in 0.9.0a2, which adds identifier quoting and validation. As a workaround, only configure schema names from trusted deployment configuration.

Affected products

How to fix

Upgrade to a fixed version: eidetic-labs stigmem 0.9.0a2. Check the vendor advisory for mitigations.
