Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Start learningUpgrade com.linecorp.armeria:armeria
to version 1.24.3 or higher.
com.linecorp.armeria:armeria is an asynchronous HTTP/2 RPC/REST client/server library built on top of Java 8, Netty, Thrift and gRPC (armeria)
Affected versions of this package are vulnerable to Incorrect Authorization. When Spring integration is used, Armeria calls Spring controllers via TomcatService
or JettyService
with the path that may contain matrix variables. The Armeria decorators might not be invoked because of the matrix variables. If an attacker sends a specially crafted request, the request may bypass the authorizer.
Users who are unable to upgrade to the fixed version can add decorators using regex. e.g. regex:^/important.*
// Spring controller
@GetMapping("/important/resources")
public String important() {...}
// Armeria decorator
ServerBuilder sb = ...
sb.decoratorUnder("/important/", authService);
If an attacker sends a request with /important;a=b/resources
, the request would bypass the authorizer.
