brace-expansion: Brace-expansion: Denial of Service via memory exhaustion in expand() function

A flaw was found in brace-expansion. A remote attacker can exploit this vulnerability by providing specially crafted input to the expand function, which can lead to excessive memory consumption. This can cause a denial of service DoS by crashing the application due to an out-of-memory error...

kin-openapi: ValidationHandler.Load() Fail-Open Authentication Bypass via NoopAuthenticationFunc Default

Summary ValidationHandler.Load in getkin/kin-openapi silently replaces a nil AuthenticationFunc with NoopAuthenticationFunc, which always returns nil without performing any credential check. Because this substitution happens unconditionally when the caller omits the field, every OpenAPI security...

Improper Authentication

Overview Affected versions of this package are vulnerable to Improper Authentication due to the unconditional substitution of a nil AuthenticationFunc with a no-op function in the Load process. An attacker can gain unauthorized access to protected endpoints by sending unauthenticated requests, as...
