Description OSIDB Bzimport 2026-09-30 10:52:53 UTC 
A flaw was found in StackRox / RHACS Central. Central accepts the same valid SAML response repeatedly at the SAML Assertion Consumer Service (ACS) endpoint and issues a fresh authentication token each time. The signed SAML response is validated, but consumed response or assertion identifiers are not recorded or rejected afterward. An attacker who obtains a valid, unexpired signed SAML response can replay it to obtain additional distinct Central tokens for the mapped identity. This is not a signature bypass.
