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. ## CVSS-Vektor ``` CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N ``` | Metrik | Wert | Bewertung | |---|---|---| | AV Angriffsvektor | Netzwerk | bad | | AC Komplexität | Hoch | good | | PR Privilegien | Gering | warn | | UI Interaktion | Keine | bad | | S Scope | Verändert | bad | | C Vertraulichkeit | Gering | warn | | I Integrität | Keine | good | | A Verfügbarkeit | Keine | good | ## Patch verfügbar (OSV) - 3f31f094eb4f99587607af0085d4fb35461454a1 (Commit) ## Referenzen - - --- _Exportiert aus dem [tsecurity.de CVE-Dossier](https://tsecurity.de/cve?cve=CVE-2026-77573) · Datenquellen: EUVD (ENISA), NVD, OSV, CISA KEV, FIRST EPSS, Exploit-DB, BSI BITS_
