## What is CVE-2026-14524?

CVE-2026-14524 is a critical path traversal vulnerability in ProSolution WP Client, published on 16 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The ProSolution WP Client plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the proSol_fileDeleteProcess function in all versions up to, and including, 2.0.8. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). An attacker must first call the proSol_fileUploadModalProcess handler to poison their own session with a path-traversal key, then call proSol_fileDeleteProcess with that key as the filename parameter; both steps require only the publicly exposed frontend nonce.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Check this codebase for CVE-2026-14524 and fix it if it is affected.

What it is: CVE-2026-14524 is a critical path traversal vulnerability in ProSolution WP Client, published on 16 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-14524 in the wild and no public exploit code.

Affected product: ProSolution WP Client. 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.
