In versions prior to 2026.8, a user permitted to manage component repository URLs can perform server-side request forgery against internal services through DNS rebinding during VCS operations. Weblate validates the hostname's first DNS resolution, but the external VCS clients that later connect perform a separate DNS lookup, so an attacker-controlled hostname that initially resolves to a public address can be re-pointed to an internal or private address before the connection is made. By triggering a clone, fetch, push, or similar remote operation, the attacker can cause Weblate to reach internal VCS-compatible services and potentially expose private repository contents. Installations that permit untrusted repository hostnames while using VCS_RESTRICT_PRIVATE=True are affected. This issue is fixed in version 2026.8."}],"source":{"advisory":"GHSA-45m9-pf98-8jmq","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-27T14:18:19.206715Z","id":"CVE-2026-77573","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-27T14:18:46.470Z"}}]}}
