How to Fix CVE-2025-1300

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

codechecker fixed: 6.24.6 
pip install codechecker>=6.24.6
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 codechecker

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-1300, inspect your installed packages using pip:

pip show codechecker

Analyze the terminal output to locate any version of Codechecker in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.24.6), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. In Codechecker, 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

Summary --- CodeChecker versions up to 6.24.5 contain an open redirect vulnerability due to missing protections against multiple slashes after the product name in the URL's path segment. This results in bypassing protections against CVE-2021-28861, leading to the same open redirect pathway. Details --- CodeChecker processes GET requests by first rewriting the path segment of the URL, and then passing the rewritten URL to the webserver framework. When trimming the product name from the URL, no sanitization was performed on the remaining URL, which reintroduced the same issue as CVE-2021-28861, leading to the same open redirect pathway using URLs such as `/Default//attacker.com/%2f..`. Impact --- The vulnerability allows an attacker to create a hyperlink that looks like a legitimate CodeChecker URL, but redirects to an attacker-supplied website when clicked.
