Summary
OpenAM from 14.5.1 before 16.1.4 contains a cross-site request forgery vulnerability in the OAuth 2.0 device authorization flow that allows attackers to approve device codes when consent is skipped for implied-consent clients. Attackers can start a device authorization and lure a logged-in user to a crafted page, obtaining access and ID tokens to call APIs as that user.

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.
The maintainers of OpenIdentityPlatform/OpenAM published their own advisory on GitHub. Reviewed sources take precedence over it.
