CVE-2026-9096 Details
Description
Casdoor versions 2.362.0 and earlier do not enforce SAML assertion time bounds. The gosaml2 library reports all time-validation results, including NotOnOrAfter and NotBefore, in the assertionInfo.WarningInfo field. However, ParseSamlResponse() never reads this field, meaning that time bounds are computed by the library but silently discarded before the user session is issued.
A vulnerability exists in Casdoor versions through 2.362.0, where the application fails to properly enforce time bounds on SAML assertions. The gosaml2 library calculates time validations, including 'NotOnOrAfter' and 'NotBefore' conditions, but these are reported in the 'assertionInfo.WarningInfo' field, which is not read by Casdoor's 'ParseSamlResponse()' function'. As a result, time-bound validations are effectively ignored, allowing assertions to be accepted even if they are expired or not yet valid, before the user session is created.
