What is CVE-2026-9095?
CVE-2026-9095 is a high-severity authentication bypass vulnerability in Casdoor, published on 28 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Casdoor versions 2.362.0 and earlier map SAML assertions to user sessions without replay protection. The ParseSamlResponse() function in object/saml_sp.go calls sp.RetrieveAssertionInfo() and immediately maps the result to a user session. There is no assertion ID cache, OneTimeUse condition enforcement, or replay detection anywhere in the SAML SP code path. As a result, an attacker can replay a previously captured SAML assertion to obtain an authenticated session for the assertion’s subject, including administrator accounts, without needing the user’s password or MFA credentials.
Weakness: CWE-294
