## What is CVE-2025-30343?

CVE-2025-30343 is a low-severity path traversal vulnerability in Intevation OpenSlides, published on 21 Mar 2025. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

A directory traversal issue was discovered in OpenSlides before 4.2.5. Files can be uploaded to OpenSlides meetings and organized in folders. The interface allows users to download a ZIP archive that contains all files in a folder and its subfolders. If an attacker specifies the title of a file or folder as a relative or absolute path (e.g., ../../../etc/passwd), the ZIP archive generated for download converts that title into a path. Depending on the extraction tool used by the user, this might overwrite files locally outside of the chosen directory.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), CWE-24 (Path Traversal: '../filedir')

Check this codebase for CVE-2025-30343 and fix it if it is affected.

What it is: CVE-2025-30343 is a low-severity path traversal vulnerability in Intevation OpenSlides, published on 21 Mar 2025. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-30343 exists.

Affected product: Intevation OpenSlides. 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.
