GHSA-w7pm-9g55-mxfm
stigmem-node's unsigned plugin override could be enabled without a second explicit acknowledgment
Blast Radius
stigmem-nodeReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
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]'

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for stigmem-node. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update stigmem-node to 0.9.0a2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-w7pm-9g55-mxfm is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-w7pm-9g55-mxfm is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-w7pm-9g55-mxfm. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-w7pm-9g55-mxfm in your dependencies?
O3 detects GHSA-w7pm-9g55-mxfm across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
