How to Fix CVE-2023-33290

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 
Upgrade git-url-parse to 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: 

inspect dependencies for git-url-parse

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-33290, inspect your project dependencies for Git url parse:

inspect dependencies for 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: Verify declared build manifests and deployed runtime container environments.

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

The git-url-parse crate through 0.4.4 for Rust allows Regular Expression Denial of Service (ReDos) via a crafted URL to `normalize_url` in `lib.rs`, a similar issue to CVE-2023-32758 (Python).
