Summary
stigmem-node's unsigned plugin override could be enabled without a second explicit acknowledgment
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]'

- Release: https://github.com/eidetic-labs/stigmem/releases/tag/v0.9.0a2
- Changelog: https://github.com/eidetic-labs/stigmem/blob/v0.9.0a2/CHANGELOG.md#L14-L35
- Security policy and posture: https://github.com/eidetic-labs/stigmem/blob/v0.9.0a2/SECURITY.md
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.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Patched in 0.9.0a2. Disabling plugin signature enforcement now requires a second explicit acknowledgment value.
Frequently Asked Questions
- What is GHSA-W7PM-9G55-MXFM? GHSA-W7PM-9G55-MXFM is a high-severity security vulnerability in stigmem-node (pip), affecting versions < 0.9.0a2. It is fixed in 0.9.0a2.
- Which versions of stigmem-node are affected by GHSA-W7PM-9G55-MXFM? stigmem-node (pip) versions < 0.9.0a2 is affected.
- Is there a fix for GHSA-W7PM-9G55-MXFM? Yes. GHSA-W7PM-9G55-MXFM is fixed in 0.9.0a2. Upgrade to this version or later.
- Is GHSA-W7PM-9G55-MXFM exploitable, and should I be worried? Whether GHSA-W7PM-9G55-MXFM is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-W7PM-9G55-MXFM is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
