Grease: An Open-Source Tool for Uncovering Hidden Vulnerabilities in Binary Code (galois.com)
Proactively and defensively ensuring the absence of vulnerabilities in binary code is crucial for deploying high-assurance systems. GREASE is an open-source tool leveraging under-constrained symbolic execution to help software reverse engineers analyze binaries and uncover hard-to-spot bugs, ultimately enhancing system security. This kind of binary analysis is especially important for systems that include COTS software that is only provided in binary form.

Sign in as anyone: Bypassing SAML SSO authentication with parser differentials (github.blog)
Critical authentication bypass vulnerabilities (CVE-2025-25291 + CVE-2025-25292) were discovered in ruby-saml up to version 1.17.0. Attackers who are in possession of a single valid signature that was created with the key used to validate SAML responses or assertions of the targeted organization can use it to construct SAML assertions themselves and are in turn able to log in as any user.
