## What is CVE-2025-46825?

CVE-2025-46825 is a low-severity cross-site scripting vulnerability in kanboard, published on 12 May 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Kanboard is project management software that focuses on the Kanban methodology. Versions 1.2.26 through 1.2.44 have a Stored Cross-Site Scripting (XSS) Vulnerability in the `name` parameter of the `http://localhost/?controller=ProjectCreationController&action=create` form. This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users. Note that the default content security policy (CSP) blocks the JavaScript attack, though it can be exploited if an instance is badly configured and the software is vulnerable to CSS injection because of the unsafe-inline on the default CSP. Version 1.2.45 contains a fix for the issue.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

What it is: CVE-2025-46825 is a low-severity cross-site scripting vulnerability in kanboard, published on 12 May 2025. An attacker can exploit it over the internet without logging in, 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-2025-46825 exists.

Affected product: kanboard. 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.
