Description
A security flaw has been discovered in wonderwhy-er DesktopCommanderMCP up to 0.2.38. This impacts an unknown function of the file src/search-manager.ts of the component start_search. Performing a manipulation of the argument SearchResult[] results in inefficient regular expression complexity. It is possible to initiate the attack remotely. The exploit has been released to the public and may be used for attacks. Upgrading to version 0.2.39 will fix this issue. The patch is named 4ce845f8749b6a159b57b38dcc3357f7222a8078. It is suggested to upgrade the affected component.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @wonderwhy-er/desktop-commander. 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 @wonderwhy-er/desktop-commander to 0.2.39 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r87g-78mx-3wg4 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-r87g-78mx-3wg4 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-r87g-78mx-3wg4. 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-r87g-78mx-3wg4 in your dependencies?
O3 detects GHSA-r87g-78mx-3wg4 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
