How to Fix CVE-2023-32758

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

git-url-parse fixed: Latest secure release 
pip install git-url-parse>=Latest secure release
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 git-url-parse

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-32758, inspect your installed packages using pip:

pip show git-url-parse

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

Note: The pip show git-url-parse command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1333: Inefficient Regular Expression Complexity, where the product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential. In Git url parse, 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

giturlparse (aka git-url-parse) through 1.2.2, as used in Semgrep 1.5.2 through 1.24.1, is vulnerable to ReDoS (Regular Expression Denial of Service) if parsing untrusted URLs. This might be relevant if Semgrep is analyzing an untrusted package (for example, to check whether it accesses any Git repository at an http:// URL), and that package's author placed a ReDoS attack payload in a URL used by the package.
