CVE-2022-34621Network attack vector

Authenticated account takeover via unchecked user_id

Published Aug 19, 2022 · Updated Aug 3, 2024

IDOR in Mealie 0.5.5 and 1.0.0beta3 allows remote authenticated users to alter other users' passwords and profile data. Each exposed user_id parameter selects the account to update without an authorization check tying that account to the authenticated user. Any authenticated account can therefore reset another user's password, including an administrator's, and modify that account's profile image or other attributes.
