Weblate leaks the IP of project members inviting users to assume reviewer roles in Audit log

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 integration with Anubis can lead to Open Redirect via redir parameter

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 5.13.3.

Weblate has long session expiry times during second factor verification

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 exposes personal IP address via e-mail

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 lacks rate limiting when verifying second factor

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 VCS credentials included in URL parameters are potentially logged and saved into browser history as plaintext

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. 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 vulnerabler to improper sanitization of project backups

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.

Remote Code Execution (RCE)

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.
