## What is CVE-2024-34061?

CVE-2024-34061 is a medium-severity cross-site scripting vulnerability in dgtlmoon changedetection.io, published on 2 May 2024. 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

changedetection.io is a free open source web page change detection, website watcher, restock monitor and notification service. In affected versions Input in parameter notification_urls is not processed resulting in javascript execution in the application. A reflected XSS vulnerability happens when the user input from a URL or POST data is reflected on the page without being stored, thus allowing the attacker to inject malicious content. This issue has been addressed in version 0.45.22. Users are advised to upgrade. There are no known workarounds for this vulnerability.

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

Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-34061 exists.

Affected packages and fixed versions:
- changedetection.io (PyPI): affected all versions; fixed in 0.45.22
- changedetection-io (PyPI): affected all versions; fixed in 0.45.22
- changedetection-io (PyPI): affected all versions; fixed in 0.45.22

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.
