Vulnerability in stigmem-node (CVE-2026-76241)
Summary
Vulnerability in stigmem-node (CVE-2026-76241). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 0.9.0a2 or later.
Original description
The description as published by the source.
Impact
A single configuration flag could disable plugin signature enforcement. If an operator unintentionally carried that setting into an environment where plugin paths are writable by less-trusted users, unsigned plugin code could be loaded.
Patches
Patched in 0.9.0a2. Disabling plugin signature enforcement now requires a second explicit acknowledgment value.
Workarounds
Before upgrading, keep plugin signing required in all shared or production environments and ensure plugin directories are not writable by untrusted users.
Upgrade
Upgrade to the patched release:
pip install --upgrade --pre stigmem-node
If developers install through the Stigmem meta-package instead, they should use the matching extra for deployments, for example:
pip install --upgrade --pre 'stigmem[node]'
