Vulnerabilities (CVE)

Weblate is a web based localization tool. Prior to version 5.16.1, the REST API's `AddonViewSet` (`weblate/api/views.py`, line 2831) uses `queryset = Addon.objects.all()` without overriding `get_queryset()` to scope results by user permissions. This allows any authenticated user (or anonymous users if `REQUIRE_LOGIN` is not set) to list and retrieve ALL addons across all projects and components via `GET /api/addons/` and `GET /api/addons/{id}/`. Version 5.16.1 fixes the issue.

Weblate is a web based localization tool. Prior to 5.16.0, the SSH management console did not validate the passed input while adding the SSH host key, which could lead to an argument injection to `ssh-add`. Version 5.16.0 fixes the issue. As a workaround, properly limit access to the management console.

wlc is a Weblate command-line client using Weblate's REST API. Prior to 1.17.2, the multi-translation download could write to an arbitrary location when instructed by a crafted server. This vulnerability is fixed in 1.17.2.

Weblate is a web based localization tool. In versions prior to 5.15.1, it was possible to overwrite Git configuration remotely and override some of its behavior. Version 5.15.1 fixes the issue.

wlc is a Weblate command-line client using Weblate's REST API. Prior to 1.17.0, the SSL verification would be skipped for some crafted URLs. This vulnerability is fixed in 1.17.0.

wlc is a Weblate command-line client using Weblate's REST API. Prior to 1.17.0, wlc supported providing unscoped API keys in the setting. This practice was discouraged for years, but the code was never removed. This might cause the API key to be leaked to different servers.

Weblate is a web based localization tool. Prior to 5.15.2, the screenshot images were served directly by the HTTP server without proper access control. This could allow an unauthenticated user to access screenshots after guessing their filename. This vulnerability is fixed in 5.15.2.

Weblate is a web based localization tool. The Create Component functionality in Weblate allows authorized users to add new translation components by specifying both a version control system and a source code repository URL to pull from. However, prior to version 5.15, the repository URL field is not validated or sanitized, allowing an attacker to supply arbitrary protocols, hostnames, and IP addresses, including localhost, internal network addresses, and local filenames. When the Mercurial versi ... Weblate is a web based localization tool. The Create Component functionality in Weblate allows authorized users to add new translation components by specifying both a version control system and a source code repository URL to pull from. However, prior to version 5.15, the repository URL field is not validated or sanitized, allowing an attacker to supply arbitrary protocols, hostnames, and IP addresses, including localhost, internal network addresses, and local filenames. When the Mercurial version control system is selected, Weblate exposes the full server-side HTTP response for the provided URL. This effectively creates a server-side request forgery (SSRF) primitive that can probe internal services and return their contents. In addition to accessing internal HTTP endpoints, the behavior also enables local file enumeration by attempting file:// requests. While file contents may not always be returned, the application’s error messages clearly differentiate between files that exist and files that do not, revealing information about the server’s filesystem layout. In cloud environments, this behavior is particularly dangerous, as internal-only endpoints such as cloud metadata services may be accessible, potentially leading to credential disclosure and full environment compromise. This has been addressed in the Weblate 5.15 release. As a workaround, remove Mercurial from `VCS_BACKENDS`; the Git backend is not affected. The Git backend was already configured to block the file protocol and does not expose the HTTP response content in the error message.

Weblate is a web based localization tool. In versions prior to 5.15.1, it was possible to read arbitrary files from the server file system using crafted symbolic links in the repository. Version 5.15.1 fixes the issue.

Weblate is a web based localization tool. In versions prior to 5.15, it was possible to accept an invitation opened by a different user. Version 5.15. contains a patch. As a workaround, avoid leaving one's Weblate sessions with an invitation opened unattended.

Weblate is a web based localization tool. In versions prior to 5.15, it was possible to trigger repository updates for many repositories via a crafted webhook payload. Version 5.15 fixes the issue. As a workaround, disabling webhooks completely using ENABLE_HOOKS avoids this vulnerability.

Weblate is a web based localization tool. In versions prior to 5.15, it was possible to retrieve user notification settings or list all users via API. Version 5.15 fixes the issue.

Weblate is a web based localization tool. In versions 5.14 and below, Weblate leaks the IP address of the project member inviting the user to the project in the audit log. The audit log includes IP addresses from admin-triggered actions, which can be viewed by invited users. This issue is fixed in version 5.14.1.

Weblate is a web based localization tool. An open redirect exists in versions 5.13.2 and below via the redir parameter on .within.website when Weblate is configured with Anubis and REDIRECT_DOMAINS is not set. An attacker can craft a URL on the legitimate domain that redirects a victim to an attacker-controlled site. The redirect can also be used to initiate drive-by downloads (redirecting to a URL that serves a malicious file), increasing the risk to end users. This issue is fixed in version 5. ...

Weblate is a web based localization tool. Versions lower than 5.13.1 contain a vulnerability that causes long session expiry during the second factor verification. The long session expiry could be used to circumvent rate limiting of the second factor. This issue is fixed in version 5.13.1.

Weblate is a web based localization tool. Prior to version 5.12, the audit log notifications included the full IP address of the acting user. This could be obtained by third-party servers such as SMTP relays, or spam filters. This issue has been patched in version 5.12.

Weblate is a web based localization tool. Prior to version 5.12, the verification of the second factor was not subject to rate limiting. The absence of rate limiting on the second factor endpoint allows an attacker with valid credentials to automate OTP guessing. This issue has been patched in version 5.12.

Weblate is a web based localization tool. Prior to version 5.11, when 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.

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 logs in plaintext. If using Weblate official Docker image, nginx logs the URL and the token in plaintext. This issue is patched in version 5.11.

The password reset form in Weblate before 2.10.1 provides different error messages depending on whether the email address is associated with an account, which allows remote attackers to enumerate user accounts via a series of requests.

Weblate is a web based localization tool. Prior to version 5.6.2, Weblate didn't correctly validate filenames when restoring project backup. It may be possible to gain unauthorized access to files on the server using a crafted ZIP file. This issue has been addressed in Weblate 5.6.2. As a workaround, do not allow untrusted users to create projects.

Weblate is a copyleft software web-based continuous localization system. Versions prior to 4.11 do not properly neutralize user input used in user name and language fields. Due to this improper neutralization it is possible to perform cross-site scripting via these fields. The issues were fixed in the 4.11 release. Users unable to upgrade are advised to add their own neutralize logic.

The package weblate from 0 and before 4.11.1 are vulnerable to Remote Code Execution (RCE) via argument injection when using git or mercurial repositories. Authenticated users, can change the behavior of the application in an unintended way, leading to command execution.
