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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-20"],"references":["https://docs.varnish-software.com/security/VSV00011","https://lists.debian.org/debian-lts-announce/2022/11/msg00036.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/G6ZMOZVBLZXHEV5VRW4I4SOWLQEK5OF5/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/M4KVVCIQVINQQ2D7ORNARSYALMJUMP3I/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XGF6LFTHXCSYMYUX5HLMVXQH3WHCSFLU/"],"products":["debian:debian_linux","fedoraproject:fedora","varnish-software:varnish_cache","varnish-software:varnish_cache_plus","varnish_cache_project:varnish_cache"],"source":"nvd","synced_at":"2026-10-19T21:37:08.729216836+00:00"},"epss":{"cve":"CVE-2022-45060","score":0.01037,"percentile":0.63933,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
