How do I fix GHSA-2g7v-hghf-grg4?

Update mcp-maigret to 1.0.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2g7v-hghf-grg4 is resolved across your whole dependency graph.

How do I detect GHSA-2g7v-hghf-grg4 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mcp-maigret. 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.

How do I mitigate GHSA-2g7v-hghf-grg4 if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-2g7v-hghf-grg4?

O3 pinpoints whether GHSA-2g7v-hghf-grg4 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-2g7v-hghf-grg4 actively exploited in the wild?

No public exploit code has been indexed for GHSA-2g7v-hghf-grg4 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-2g7v-hghf-grg4?

GHSA-2g7v-hghf-grg4 has an EPSS (Exploit Prediction Scoring System) score of 1.6%, placing it in the 72th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

Description

A vulnerability was determined in BurtTheCoder mcp-maigret up to 1.0.12. This affects an unknown part of the file src/index.ts of the component search_username. Executing a manipulation of the argument Username can lead to command injection. The attack may be launched remotely. Upgrading to version 1.0.13 is able to mitigate this issue. This patch is called b1ae073c4b3e789ab8de36dc6ca8111ae9399e7a. Upgrading the affected component is advised.
