DescriptionCVE.org
Logto silently fails to delete IdP-initiated SAML sessions, enabling session replay and reuse within the session’s validity window.
AnalysisAI
Session replay in Logto IdP-initiated SAML sessions allows unauthenticated remote attackers to reuse captured session tokens, leading to unauthorized account access. Affected versions 1.21.0 through 1.37.1 silently fail to delete sessions, enabling replay within the session's validity window. No active exploitation confirmed but the attack requires no user interaction, and EPSS indicates very low exploitation likelihood.
