## What is CVE-2026-0522?

CVE-2026-0522 is a high-severity path traversal vulnerability in VertiGIS FM, published on 1 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

A local file inclusion vulnerability in the upload/download flow of the VertiGIS FM application allows authenticated attackers to read arbitrary files from the server by manipulating a file's path during its upload. When the file is subsequently downloaded, the file in the attacker controlled path is returned. Due to the application's ASP.NET architecture, this could potentially lead to remote code execution when the "web.config" file is obtained. Furthermore, the application resolves UNC paths which may enable NTLM-relaying attacks.

This issue affects VertiGIS FM: 10.5.00119 (0d29d428).

Weakness: CWE-610 (Externally Controlled Reference to a Resource in Another Sphere)

Check this codebase for CVE-2026-0522 and fix it if it is affected.

What it is: CVE-2026-0522 is a high-severity path traversal vulnerability in VertiGIS FM, published on 1 Apr 2026. 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-2026-0522 exists.

Affected product: VertiGIS FM. 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.
