CVE-2026-76240

stigmem Postgres SQL Injection via Schema Identifier

Published Aug 19, 2026 CVSS 4.0 · 7.5 High EPSS < 1% KEV · Not listed
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.
