## What is GHSA-c39w-3pjx-qc7m?

GHSA-c39w-3pjx-qc7m is a cross-site scripting vulnerability in leantime/leantime, published on 21 Feb 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

### Description
Leantime allows stored cross-site scripting (XSS) in the API key name while generating the API key.

Any low privileged user like manager, or editor, can create an API key with XSS payload. When admin will visit the Company page, the XSS will automatically get triggerred leading to the unauthorized action performed from the ADMIN account. Like, removing any user, or adding someone else as high privilege, and many more.

Check this codebase for GHSA-c39w-3pjx-qc7m and fix it if it is affected.

What it is: GHSA-c39w-3pjx-qc7m is a cross-site scripting vulnerability in leantime/leantime, published on 21 Feb 2025. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of GHSA-c39w-3pjx-qc7m in the wild and no public exploit code.

Affected packages and fixed versions:
- leantime/leantime (Packagist): affected all versions; fixed in 3.3
- leantime/leantime (Packagist): affected all versions; fixed in 3.3

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.
