How to Fix GHSA-rxq3-5249-8hgg

To remediate this vulnerability, upgrade all affected Personnummer dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

personnummer fixed: 3.0.2 
pip install personnummer>=3.0.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show personnummer

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-rxq3-5249-8hgg, inspect your installed packages using pip:

pip show personnummer

Analyze the terminal output to locate any version of Personnummer in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.2), your application is affected.

Note: The pip show personnummer command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Personnummer, 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.

Source Advisory Statement

This vulnerability was reported to the personnummer team in June 2020. The slow response was due to locked ownership of some of the affected packages, which caused delays to update packages prior to disclosure. The vulnerability is determined to be low severity. ### Impact This vulnerability impacts users who rely on the for last digits of personnummer to be a _real_ personnummer. ### Patches The issue have been patched in all repositories. The following versions should be updated to as soon as possible: [C#](https://github.com/advisories/GHSA-qv8q-v995-72gr) 3.0.2 D 3.0.1 [Dart](https://github.com/advisories/GHSA-4xh4-v2pq-jvhm) 3.0.3 Elixir 3.0.0 [Go](https://github.com/advisories/GHSA-hv53-vf5m-8q94) 3.0.1 [Java](https://github.com/advisories/GHSA-q3vw-4jx3-rrr2) 3.3.0 [JavaScript](https://github.com/advisories/GHSA-vpgc-7h78-gx8f) 3.1.0 Kotlin 1.1.0 Lua 3.0.1 [PHP](https://github.com/advisories/GHSA-2p6g-gjp8-ggg9) 3.0.2 Perl 3.0.0 [Python](https://github.com/advisories/GHSA-rxq3-5249-8hgg) 3.0.2 [Ruby](https://github.com/advisories/GHSA-vp9c-fpxx-744v) 3.0.1 [Rust](https://github.com/advisories/GHSA-28r9-pq4c-wp3c) 3.0.0 Scala 3.0.1 Swift 1.0.1 If you are using any of the earlier packages, please update to latest. ### Workarounds The issue arrieses from the regular expression allowing the first three digits in the last four digits of the personnummer to be 000, which is invalid. To mitigate this without upgrading, a check on the last four digits can be made to make sure it's not 000x. ### For more information If you have any questions or comments about this advisory: * Open an issue in [Personnummer Meta](https://github.com/personnummer/meta/issues) * Email us at [Personnummer Email](mailto:security@personnummer.dev)
