CVSS: 7.8EPSS: 0%CPEs: 63EXPL: 0CVE-2022-45060 – varnish: Request Forgery Vulnerability
https://notcve.org/view.php?id=CVE-2022-45060
09 Nov 2022 — An HTTP Request Forgery issue was discovered in Varnish Cache 5.x and 6.x before 6.0.11, 7.x before 7.1.2, and 7.2.x before 7.2.1. An attacker may introduce characters through HTTP/2 pseudo-headers that are invalid in the context of an HTTP/1 request line, causing the Varnish server to produce invalid HTTP/1 requests to the backend. This could, in turn, be used to exploit vulnerabilities in a server behind the Varnish server. Note: the 6.0.x LTS series (before 6.0.11) is affected.
