+  "summary": "OpenBao lacks user confirmation for OIDC direct callback mode",
+  "details": "### Impact\n\nOpenBao does not prompt for user confirmation when logging in via JWT/OIDC and a role with `callback_mode` set to `direct`.\n\nThis allows an attacker to start an authentication request and perform \"remote phishing\" by having the victim visit the URL and automatically log-in to the session of the attacker. Despite being based on the authorization code flow, the  `direct` mode calls back directly to the API and allows an attacker to poll for an OpenBao token until it is issued.\n\n### Patches\nVersion 2.5.2 includes an additional confirmation screen for `direct` type logins that requires manual user interaction in order to finish the authentication.\n\n### Workarounds\nThis issue can be worked around either by removing any roles with `callback_mode=direct` or enforcing confirmation for every session on the token issuer side for the Client ID used by OpenBao.",
