| CVE-2022-23959 | Cri | 0.59 | 9.1 | 0.02 | Jan 26, 2022 | In Varnish Cache before 6.6.2 and 7.x before 7.0.2, Varnish Cache 6.0 LTS before 6.0.10, and and Varnish Enterprise (Cache Plus) 4.1.x before 4.1.11r6 and 6.0.x before 6.0.9r4, request smuggling can occur for HTTP/1 connections. | ||
| CVE-2024-30156 | Hig | 0.49 | 7.5 | 0.04 | Mar 24, 2024 | Varnish Cache before 7.3.2 and 7.4.x before 7.4.3 (and before 6.0.13 LTS), and Varnish Enterprise 6 before 6.0.12r6, allows credits exhaustion for an HTTP/2 connection control flow window, aka a Broke Window Attack. | ||
| CVE-2022-45060 | Hig | 0.49 | 7.5 | 0.01 | Nov 9, 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… | ||
| CVE-2022-38150 | Hig | 0.49 | 7.5 | 0.01 | Aug 11, 2022 | In Varnish Cache 7.0.0, 7.0.1, 7.0.2, and 7.1.0, it is possible to cause the Varnish Server to assert and automatically restart through forged HTTP/1 backend responses. An attack uses a crafted reason phrase of the backend response status line. This is fixed in 7.0.3 and 7.1.1. | ||
| CVE-2020-11653 | Hig | 0.49 | 7.5 | 0.02 | Apr 8, 2020 | An issue was discovered in Varnish Cache before 6.0.6 LTS, 6.1.x and 6.2.x before 6.2.3, and 6.3.x before 6.3.2. It occurs when communication with a TLS termination proxy uses PROXY version 2. There can be an assertion failure and daemon restart, which causes a performance loss. | ||
| CVE-2019-20637 | Hig | 0.49 | 7.5 | 0.02 | Apr 8, 2020 | An issue was discovered in Varnish Cache before 6.0.5 LTS, 6.1.x and 6.2.x before 6.2.2, and 6.3.x before 6.3.1. It does not clear a pointer between the handling of one client request and the next request within the same connection. This sometimes causes information to be… | ||
| CVE-2019-15892 | Hig | 0.49 | 7.5 | 0.06 | Sep 3, 2019 | An issue was discovered in Varnish Cache before 6.0.4 LTS, and 6.1.x and 6.2.x before 6.2.1. An HTTP/1 parsing failure allows a remote attacker to trigger an assert by sending crafted HTTP/1 requests. The assert will cause an automatic restart with a clean cache, which makes it… | ||
| CVE-2017-12425 | Hig | 0.49 | 7.5 | 0.02 | Aug 4, 2017 | An issue was discovered in Varnish HTTP Cache 4.0.1 through 4.0.4, 4.1.0 through 4.1.7, 5.0.0, and 5.1.0 through 5.1.2. A wrong if statement in the varnishd source code means that particular invalid requests from the client can trigger an assert, related to an Integer Overflow.… | ||
| CVE-2015-8852 | Hig | 0.42 | 7.5 | 0.04 | Apr 25, 2016 | Varnish 3.x before 3.0.7, when used in certain stacked installations, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via a header line terminated by a \r (carriage return) character in conjunction with multiple Content-Length… | ||
| CVE-2025-30346 | Med | 0.35 | 5.4 | 0.00 | Mar 21, 2025 | Varnish Cache before 7.6.2 and Varnish Enterprise before 6.0.13r10 allow client-side desync via HTTP/1 requests. | ||
| CVE-2009-2936 | 0.08 | — | 0.64 | Apr 5, 2010 | The Command Line Interface (aka Server CLI or administration interface) in the master process in the reverse proxy server in Varnish before 2.1.0 does not require authentication for commands received through a TCP port, which allows remote attackers to (1) execute arbitrary code… | |||
| CVE-2021-36740 | Med | 0.00 | 6.5 | 0.02 | Jul 14, 2021 | Varnish Cache, with HTTP/2 enabled, allows request smuggling and VCL authorization bypass via a large Content-Length header for a POST request. This affects Varnish Enterprise 6.0.x before 6.0.8r3, and Varnish Cache 5.x and 6.x before 6.5.2, 6.6.x before 6.6.1, and 6.0 LTS… | ||
| CVE-2013-4484 | 0.00 | — | 0.03 | Nov 1, 2013 | Varnish before 3.0.5 allows remote attackers to cause a denial of service (child-process crash and temporary caching outage) via a GET request with trailing whitespace characters and no URI. |
