## What is CVE-2026-40526?

CVE-2026-40526 is a high-severity path traversal vulnerability in Volmarg personal-management-system, published on 27 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Volmarg Personal Management System contains a path traversal vulnerability that allows authenticated attackers to read arbitrary files by supplying absolute filesystem paths to the GET /public/get-file/{path} endpoint. The path route parameter is passed directly to file_get_contents() without canonicalization against a permitted base directory, enabling attackers to retrieve sensitive files accessible to the PHP-FPM worker process without using directory traversal sequences.

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

Affected product: Volmarg personal-management-system. 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.
