## What is CVE-2026-25825?

CVE-2026-25825 is a low-severity path traversal vulnerability in n/a, published on 15 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

An issue was discovered in Keyfactor SignServer before 7.6.0. The output file to which SignerStatusReportWorker logs the report can be set to any path, even one that points to a file that already exists. This gives a user (with admin access) the possibility to write files in arbitrary directories in the server filesystem and potentially overwrite files accessible by the local user JBoss.

Check this codebase for CVE-2026-25825 and fix it if it is affected.

What it is: CVE-2026-25825 is a low-severity path traversal vulnerability in n/a, published on 15 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-25825 in the wild and no public exploit code.

Affected product: n/a. 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.
