Uncaught Exception

Overview Affected versions of this package are vulnerable to Uncaught Exception via the ValidationHandler process. An attacker can cause the application to panic and disrupt service availability by sending HTTP requests with non-canonical or unsupported HTTP method tokens to any existing static...

kin-openapi: Unauthenticated panic (DoS) in openapi3filter legacy router via non-canonical/unsupported HTTP method on a static path

Summary The openapi3filter.ValidationHandler the exported, documented request-validation middleware hard-wires the legacy router routers/legacy. That router matches the incoming request method verbatim against a trie built exclusively from upper-cased canonical HTTP methods. A request carrying a...

CVE-2026-111235 OpenNMS REST authorization bypass via non-canonical HTTP method

An authorization bypass vulnerability exists in the REST API of multiple versions of OpenNMS Meridian and Horizon. The /rest/ Spring Security filter chains authorize requests with intercept-url rules that name the HTTP method as an uppercase token, compare the method case-sensitively, and have no...
