GHSA-47xh-qxqv-mgvg kube-httpcache is vulnerable to Cross-Site Request Forgery (CSRF)

• Go github.com/mittwald/kube-httpcache: < 0.7.1 → fixed in 0.7.1

Impact > A request forgery attack can be performed on Varnish Cache servers that have the HTTP/2 protocol turned on. An attacker may introduce characters through the 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 may in turn be used to successfully exploit vulnerabilities in a server behind the Varnish server. > -- https://varnish-cache.org/security/VSV00011.html#vsv00011 Patches This is fixed in Varnish 6.0.11; Varnish 6.0.11 is available in `kube-httpcache` versions v0.7.1 and later. Workarounds See upstream mitigation hints. References • https://varnish-cache.org/security/VSV00011.html#vsv00011
