Summary
Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, certain federation endpoints in a non-default clustered configuration inconsistently encode user-supplied parameters rendered into HTML in the SAML2 cluster cookie-hash redirect path. An unauthenticated attacker can induce a user to follow a crafted request and execute script in the OpenAM origin. This issue is fixed in version 16.1.1.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
