Doc Text:	A flaw was found in Spring Security's WebFlux framework pattern matching, where it does not properly evaluate certain patterns. A server using path-based pattern matching in WebFlux could allow an attacker to bypass security settings for some request paths, potentially leading to information disclosure, access of functionality outside the user's permissions, or denial of service.

Description Chess Hazlett 2023-09-28 22:44:06 UTC

Using "**" as a pattern in Spring Security configuration for WebFlux creates a mismatch in pattern matching between Spring Security and Spring WebFlux, and the potential for a security bypass.
