DescriptionCVE.org
Logto omits validation of the SAML <Conditions> element, enabling attackers to strip time and audience restrictions and replay assertions indefinitely.
AnalysisAI
Remote attackers can bypass SAML assertion time and audience restrictions in Logto versions 1.12.0 through 1.37.1, enabling indefinite replay of modified assertions and unauthorized persistent access. No active exploitation or public exploit code has been identified, and EPSS indicates a low exploitation probability (0.13%).
