Published Jul 30, 2025 CWE-400 EPSS 0.39% (32th pctl)

Overview

CVE-2025-54572 is a known-severity vulnerability. It was published on July 30, 2025.

Technical Description

The Ruby SAML library is for implementing the client side of a SAML authorization. In versions 1.18.0 and below, a denial-of-service vulnerability exists in ruby-saml even with the message_max_bytesize setting configured. The vulnerability occurs because the SAML response is validated for Base64 format prior to checking the message size, leading to potential resource exhaustion. This is fixed in version 1.18.1.

Remediation
