CVE-2026-34840: Saml Assertion Wrapping Missing Length Check
Unconditional extraction of a SAML assertion element via array indexing (e.g., `assertion[0]`) without ensuring exactly one assertion is present. This weak validation pattern enables SAML Assertion Wrapping (XML Signature Wrapping) vulnerabilities. An attacker may inject an unsigned forged assertion alongside a legitimately signed assertion to bypass authent
