What is CVE-2026-76182?
CVE-2026-76182 is a medium-severity vulnerability in Eclipse Jetty, published on 15 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
In Eclipse Jetty, `TryPathsHandler` and `TryFilesFilter` can be configured to forward requests to template URIs such as `index?p=$path`, where `$path` is the request path in context.
However, URI paths may contain characters that are reserved in URI queries so that a path of `/s&a=1` when applied to the template becomes `index?p=/s&a=1`, which is interpreted as 2 query parameters: `p=/s` and `a=1`, rather than just one query parameter `p` whose value is `/s&a=1`.
Weakness: CWE-74
