EPSS

• CVE-2026-10691: 0.35% estimated exploitation activity in the next 30 days; percentile 29.17 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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 startsearch. 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.

# Patch Next advisory brief: CVE-2026-10691

Advisory: DesktopCommanderMCP is vulnerable to Uncontrolled Resource Consumption
IDs: CVE-2026-10691, GHSA-r87g-78mx-3wg4
Record: https://patchnext.com/advisories/cve-2026-10691 (revision 3, source checked 26 Oct 2026, 12:56 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 2.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @wonderwhy-er/desktop-commander 0.2.39. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @wonderwhy-er/desktop-commander: affected < 0.2.39; fixed in 0.2.39

## Suggested inspection (read-only)
- `npm ls @wonderwhy-er/desktop-commander --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on @wonderwhy-er/desktop-commander.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-r87g-78mx-3wg4 (OSV record GHSA-r87g-78mx-3wg4 lists affected ranges: npm @wonderwhy-er/desktop-commander >=0 <0.2.39 (fixed))
- Verified: https://github.com/advisories/GHSA-r87g-78mx-3wg4 (GitHub-reviewed advisory GHSA-r87g-78mx-3wg4 lists affected ranges: npm @wonderwhy-er/desktop-commander >=0 <0.2.39)
