Official description

OpenAM before 16.1.3 contains a latent cross-site scripting defect that places the SAML message, relay state and target URL unencoded into the load-balancer cookie bounce auto-submit page. If reachable with cookieHashRedirectEnabled set, crafted requests could execute script in the OpenAM origin, though an unrelated HTTP 500 failure prevents exploitation in released versions.
