CVE-2026-76240stigmem Postgres SQL Injection via Schema Identifier
High 7.5
In plain English
A high-severity SQL injection in stigmem from eidetic-labs. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 33% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official 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.
