AI-suggested
A patch is available in version 0.0.0-20260727180059-43aaccd5bfac that fixes this issue by properly binding email verification tokens to the specific email address. Users of affected versions should upgrade to this fixed version. Until patched, relying parties should avoid trusting the 'email_verified' claim alone for account linking or provisioning, or implement additional verification controls. No other immediate actions are indicated by the vendor advisory.
Description
An authenticated Pocket ID user can exploit a flaw where an email verification token remains valid after changing the account email address. The token is bound only to the user ID, not the email address, allowing the attacker to verify an email address they do not control. This leads to the system marking the new email as verified without proof of control. Consequently, relying parties that trust the verified email claim in OIDC can be tricked into linking the attacker's identity to a victim's account, enabling cross-application account takeover.
