A flaw was found in OpenBao. A missing prompt for user confirmation when logging in via the JWT/OIDC authentication method with a role configured to use `callback_mode=direct` allows an attacker to initiate an authentication request and perform a "remote phishing" attack by tricking an authenticated user into visiting a crafted URL, automatically logging the user into the session of the attacker. OpenBao: lack of user confirmation for OpenBao OIDC direct callback mode To exploit this vulnerability, an attacker needs to convince a user to visit a crafted URL, limiting the exposure of this flaw. Due to this reason, this issue has been rated with an important severity. The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
