CVE-2026-76241stigmem Plugin Signature Enforcement Bypass via Configuration
High 7.3
In plain English
A high-severity security flaw 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 0.1% (higher than 2% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
stigmem-node 0.9.0a1 allows plugin signature enforcement to be disabled via a single configuration flag without a second explicit acknowledgment. If that setting is carried into an environment where plugin directories are writable by less-trusted users, unsigned (potentially malicious) plugin code could be loaded and executed, resulting in arbitrary code execution. Fixed in 0.9.0a2, which requires a second explicit acknowledgment to disable signature enforcement.
