0 CVE-2026-77573 is a time-of-check to time-of-use (TOCTOU) race condition vulnerability in Weblate versions prior to 2026.8. It allows a user with permission to manage component repository URLs to perform server-side request forgery (SSRF) against internal services via DNS rebinding during version control system (VCS) operations. The vulnerability arises because Weblate validates the hostname's initial DNS resolution but the external VCS clients perform a separate DNS lookup later, enabling an attacker-controlled hostname to be redirected to internal or private addresses. This can lead to unauthorized access to internal VCS-compatible services and potential exposure of private repository contents. The issue affects installations that allow untrusted repository hostnames while using the VCS_RESTRICT_PRIVATE=True setting. The vulnerability is fixed in Weblate version 2026.8.
