CVE-2025-32021: Weblate VCS Credentials Included Vulnerability
LOWCVE-2025-32021 is a LOW (CVSS 2.2) vcs credentials included vulnerability (CWE-598: Use of HTTP Request With Sensitive Query String) affecting Weblate libraries in the PyPI ecosystem. The issue involves vcs credentials included in url parameters are potentially logged and saved into browser history as plaintext. Remediation is available by upgrading affected packages to version 5.11.
CVE-2025-32021 at a Glance
Security Impact
CVSS: 2.2
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N).
How to Fix CVE-2025-32021
To remediate this vulnerability, upgrade all affected Weblate 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 weblate>=5.11
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show weblate
How to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2025-32021, inspect your installed packages using pip:
pip show weblate
Analyze the terminal output to locate any version of Weblate in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.11), your application is affected.
Note: The pip show weblate command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-598: Use of HTTP Request With Sensitive Query String, where the web application uses an http method to process a request, but the request includes sensitive information in the query string. In Weblate, 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.

"details" : "### Summary\n\nWhen creating a new component from an existing component that has a source code repository URL specified in settings, this URL is included in the client's URL parameters during the creation process. If, for example, the source code repository URL contains GitHub credentials, the confidential PAT and username are shown in plaintext and get saved into browser history. Moreover, if the request URL is logged, the credentials are written to the logs in plaintext.\n\nThe problematic URL in question is of this form:\n\n```\nhttps://<HOST>/create/component/vcs/?repo=https%3A%2F%2F<GITHUB USERNAME>%3A<GITHUB PAT>%40github.com%2F<REPOSITORY OWNER>%2F<REPOSITORY NAME>.git&project=1&category=&name=<REDACTED>&slug=<REDACTED>&is_glossary=False&vcs=github&source_language=228&license=&source_component=1#existing\n```\n\nIf using Weblate official Docker image, nginx logs the URL and the token in plaintext:\n\n```\nnginx stdout | 127.0.0.1 - - [04/Apr/2025:10:46:54 +0000] \"GET /create/component/vcs/?repo=https%3A%2F%2F<GITHUB USERNAME>%3A<GITHUB PAT>%40github.com%2F<REPOSITORY OWNER>%2F<REPOSITORY NAME>.git&project=1&category=&name=<REDACTED>&slug=<REDACTED>&is_glossary=False&vcs=github&source_language=228&license=&source_component=1 HTTP/1.1\" 200 17625 \"<REDACTED>\" \"Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:136.0) Gecko/20100101 Firefox/136.0\"\n```\n\n### Reproduction\n\n1. In a project, create a component which has the _Repository push URL_ setting configured with, for example, a GitHub repository URL including a username and a PAT.\n2. In the same project, create another component using the _From existing component_ option and selecting the previous component as the source. Click _Continue_.\n3. Observe that the URL parameter `repo` includes the secret PAT configured in the original components settings. The URL with the token is potentially saved as plaintext in browser history and server logs.\n4. Select a translation file to import and click _Continue_.\n5. Observe again the same `repo` parameter in the URL.\n\n### Impact\n\n- If server logs are compromised, the attacker may be able to gain access to private repositories potentially containing sensitive source code.\n- Under common browser settings, the URL containing VCS credentials is saved into browser history. Browser extensions, for example, are often able to read the history and thus offer a realistic attack vector to gain access to the credentials.",
