Short explanation
Versions of OpenAM prior to 16.1.4 do not validate the RelayState parameter, allowing attackers to craft SSO links with malicious RelayState and redirect users to external phishing sites. This constitutes a low‑severity open redirect exploit.
Victims can be sent from a trusted OpenAM session to phishing pages, risking credential theft.
What should be done?
- Upgrade OpenAM to version 16.1.4 or later
- Configure a relayStateUrlList to restrict allowed destinations
- Add validation for RelayState values
- Monitor vendor advisory for updates

Show the technical text from the sources
OpenAM before 16.1.4 contains an open redirect vulnerability that allows attackers to redirect users to external sites because RelayState is unchecked when no relayStateUrlList is configured. Attackers can craft single sign-on links with a malicious RelayState to send users from the trusted OpenAM origin to phishing sites and bypass URL filters.
