CVE-2025-7365
When an authenticated attacker attempts to merge accounts with another existing account during an identity provider (IdP) login, the attacker will subsequently be prompted to "review profile" information.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A flaw was found in Keycloak. When an authenticated attacker attempts to merge accounts with another existing account during an identity provider (IdP) login, the attacker will subsequently be prompted to "review profile" information. This vulnerability allows the attacker to modify their email address to match that of a victim's account, triggering a verification email sent to the victim's email address. The attacker's email address is not present in the verification email content, making it a potential phishing opportunity. If the victim clicks the verification link, the attacker can gain access to the victim's account.
