## What is CVE-2024-51483?

CVE-2024-51483 is a medium-severity path traversal vulnerability in dgtlmoon changedetection.io, published on 1 Nov 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

changedetection.io is free, open source web page change detection software. Prior to version 0.47.5, when a WebDriver is used to fetch files, `source:file:///etc/passwd` can be used to retrieve local system files, where the more traditional `file:///etc/passwd` gets blocked. Version 0.47.5 fixes the issue.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-51483 exists.

Affected packages and fixed versions:
- changedetection.io (PyPI): affected all versions; fixed in 0.47.5
- changedetection-io (PyPI): affected all versions; fixed in 0.47.5
- changedetection-io (PyPI): affected all versions; fixed in 0.47.5

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.
