{"apiVersion":"1.0","identifier":"CVE-2026-77573","description":"Weblate is a web-based continuous localization platform used to manage software translations. 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.","publishedAt":"2026-08-26T21:16:41","lastModifiedAt":"2026-08-27T17:20:24","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-77573","cvssScore":3.5,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N","epssProbability":0.00142,"riskScore":0.35,"affectedProduct":"Weblate","affectedVersions":"<2026.8","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-77573","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-77573","en":"https://www.redsauce.net/en/cves/CVE-2026-77573","fr":"https://www.redsauce.net/fr/cves/CVE-2026-77573","pt":"https://www.redsauce.net/pt/cves/CVE-2026-77573","de":"https://www.redsauce.net/de/cves/CVE-2026-77573","sk":"https://www.redsauce.net/sk/cves/CVE-2026-77573","el":"https://www.redsauce.net/el/cves/CVE-2026-77573"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-77573"}}
