CVE-2025-46705Network attack vector

Remote process crash via unexpected SAML node

Published Nov 5, 2025 · Updated Nov 5, 2025

Reachable assertion in Entr'ouvert Lasso 2.5.1 and 2.8.2 allows remote attackers to crash SAML-consuming processes via malformed XML. In lasso_node_impl_init_from_xml, XML nodes that are neither comments nor XML_ELEMENT_NODE values fall through to g_assert_not_reached instead of being rejected. The assertion is enabled by default, so unauthenticated delivery to an application that parses the response terminates its process without data disclosure or modification.
