## What is CVE-2026-24071?

CVE-2026-24071 is a high-severity vulnerability in Native Access, published on 2 Feb 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

It was found that the XPC service offered by the privileged helper of Native Access  uses the PID of the connecting client to verify its code signature. This is considered insecure and can be exploited by PID reuse attacks. The connection handler function uses _xpc_connection_get_pid(arg2) as argument for the hasValidSignature function. This value can not be trusted since it is vulnerable to PID reuse attacks.

Weakness: CWE-367 (Time-of-check Time-of-use (TOCTOU) Race Condition)

Check this codebase for CVE-2026-24071 and fix it if it is affected.

What it is: CVE-2026-24071 is a high-severity vulnerability in Native Access, published on 2 Feb 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-24071 exists.

Affected product: Native Access. 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.
