Security Impact
CVSS: 6.5
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N).
How to Fix CVE-2024-51483
To remediate this vulnerability, upgrade all affected Changedetection.io dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
pip install changedetection.io>=0.47.5Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show changedetection.ioHow to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2024-51483, inspect your installed packages using pip:
pip show changedetection.ioAnalyze the terminal output to locate any version of Changedetection.io in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.47.5), your application is affected.
Note: The pip show changedetection.io command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Changedetection.io, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.
