CVE-2025-49134Network attack vector

IP address disclosure via audit notification e-mails

Published Jun 16, 2025 · Updated Jun 17, 2025

Information disclosure in Weblate before 5.12 allows attackers to read users' full IP addresses from audit notification e-mails. The notify_auditlog task placed AuditLog.address directly into the notification template instead of using an anonymized network address. Exposure requires audit-log e-mail notifications and a recipient, SMTP relay, or spam filter outside the acting user's trust boundary.
