Machine-written summary

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

The stigmem-node package is affected in versions before 0.9.0a2. A single configuration flag could turn off plugin signature enforcement, so if that setting carried into an environment where less-trusted users can write plugin paths, unsigned plugin code could be loaded. Upgrade to 0.9.0a2, which now requires a second explicit acknowledgment value before signature enforcement can be disabled.

Written 5 Nov 2026.
