When an organization administrator configures an upstream registry for proxy caching, Quay makes a network connection to the specified registry hostname without verifying that it points to a legitimate external service. An attacker with organization administrator privileges could supply a crafted hostname to force the Quay server to make requests to internal network services, cloud infrastructure endpoints, or other resources that should not be accessible from the Quay application. ## CVSS-Vektor ``` CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:L/A:N ``` | Metrik | Wert | Bewertung | |---|---|---| | AV Angriffsvektor | Netzwerk | bad | | AC Komplexität | Gering | bad | | PR Privilegien | Hoch | good | | UI Interaktion | Erforderlich | good | | S Scope | Unverändert | good | | C Vertraulichkeit | Hoch | bad | | I Integrität | Gering | warn | | A Verfügbarkeit | Keine | good | ## Referenzen - - - - - - - - - - - --- _Exportiert aus dem [tsecurity.de CVE-Dossier](https://tsecurity.de/cve?cve=CVE-2026-32591) · Datenquellen: EUVD (ENISA), NVD, OSV, CISA KEV, FIRST EPSS, Exploit-DB, BSI BITS_
