Machine-written summary

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

TYPO3 CMS (typo3/cms-core) versions 12.0.0 to before 12.4.37 and 13.0.0 to before 13.4.18 generate passwords with insufficient entropy, because a deterministic three-character prefix is included. This makes brute-force attacks faster. The source does not state what access an attacker needs. Upgrade to 12.4.37 or 13.4.18; no workaround is listed.
