AI-suggested

European organizations should immediately upgrade Weblate installations to version 5.13.3 or later to remediate the vulnerability. If upgrading is not immediately feasible, administrators should configure the REDIRECT_DOMAINS setting to explicitly whitelist trusted domains, preventing arbitrary redirects. Implement strict URL validation and sanitization on any user-controllable redirect parameters. Educate users about the risks of clicking on unexpected or suspicious links, especially those appearing to originate from trusted internal tools. Employ web security gateways or URL filtering solutions to detect and block known malicious redirect destinations. Monitor Weblate logs for unusual redirect parameter usage or spikes in redirect traffic. Integrate multi-factor authentication and endpoint protection to reduce the impact of potential phishing or malware delivery. Finally, maintain an incident response plan that includes phishing detection and user awareness training tailored to localization and development teams.

Description

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.
