source listedECOSYSTEM: introduced 1.16.0; fixed 1.16.3
### Background In order to implement support for the SAML Enhanced Client or Proxy profile, the credentials obtained for authentication were stored in the state in order to pass them to the relevant routines. This, however, led to the credentials being recorded in the user’s session, which can be stored in permanent storage such as the local file system or a remote memcache or database server. ### Description When an authentication request is received via the ECP profile, the username and password obtained this way were saved to the state array, which is used to pass relevant data to different routines that may need it. This is not a problem in itself. However, when the ECP profile is disabled in the Identity Provider, other bindings such as HTTP-POST or HTTP-Redirect will be used, and since redirections are involved, the state array is then persisted to the user’s session, effectively storing it in the session backend. The ECP profile, which uses the SOAP and PAOS bindings, does not involve any HTTP redirection for the user, and for that reason the state array containing the credentials is never persisted to the session. The logic for determining when to save the credentials to

What to do next
- vendor patch
The original advisory lists fixed boundaries 1.16.3 for simplesamlphp/simplesamlphp. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
