Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

ApostropheCMS versions before 4.33.0 (npm package apostrophe) do not apply the login module's failed-attempt throttling or lockout to the authenticated password-change endpoint, so the current password can be guessed repeatedly. An attacker needs a valid authenticated session, such as one obtained or hijacked, and could then guess the current password and, if successful, change the account password. Upgrade to apostrophe 4.33.0 or later.
