GHSA-9pc9-4crj-mhpj: stigmem-node (CVE-2026-76240)

Package	Ecosystem	Affected	Fixed in
stigmem-node	PyPI	<0.9.0a2	0.9.0a2

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

stigmem-node versions before 0.9.0a2 interpolated Postgres schema identifiers into SQL strings. The source says the schema value is operator-controlled in the reviewed code path, so exploitation is not described as currently reachable; the source states the pattern would be unsafe if future code let tenant or request input set schema names. Upgrade to stigmem-node 0.9.0a2, which adds identifier quoting and validation. Until then, set Postgres schema names only from trusted deployment configuration.
