CVE-2026-76240: Eidetic-Labs Stigmem

High severity, CVSS 7.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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

• Eidetic-Labs Stigmem: before 0.9.0a2 (fixed in 0.9.0a2)
