## What is CVE-2025-58159?

CVE-2025-58159 is a critical vulnerability in Wegia Wegia, published on 29 Aug 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

WeGIA is a Web manager for charitable institutions. Prior to version 3.4.11, a remote code execution vulnerability was identified, caused by improper validation of uploaded files. The application allows an attacker to upload files with arbitrary filenames, including those with a .php extension. Because the uploaded file is written directly to disk without adequate sanitization or extension restrictions, a spreadsheet file followed by PHP code can be uploaded and executed on the server, leading to arbitrary code execution. This is due to insufficient mitigation of CVE-2025-22133. This issue has been patched in version 3.4.11.

Weakness: CWE-94 (Improper Control of Generation of Code), CWE-434 (Unrestricted Upload of File with Dangerous Type)

What it is: CVE-2025-58159 is a critical vulnerability in Wegia Wegia, published on 29 Aug 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-58159 exists.

Affected product: Wegia Wegia. 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.
