## What is CVE-2026-32107?

CVE-2026-32107 is a high-severity vulnerability in neutrinolabs xrdp, published on 17 Apr 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

xrdp is an open source RDP server. In versions through 0.10.5, the session execution component did not properly handle an error during the privilege drop process. This improper privilege management could allow an authenticated local attacker to escalate privileges to root and execute arbitrary code on the system. An additional exploit would be needed to facilitate this. This issue has been fixed in version 0.10.6.

Weakness: CWE-273 (Improper Check for Dropped Privileges)

Check this codebase for CVE-2026-32107 and fix it if it is affected.

What it is: CVE-2026-32107 is a high-severity vulnerability in neutrinolabs xrdp, published on 17 Apr 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-32107 in the wild and no public exploit code.

Affected product: neutrinolabs xrdp. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
