12.4.37- Upgrade typo3/cms-core to this version or later
Description
A deterministic three‑character prefix in the Password Generation component of TYPO3 CMS versions 12.0.0–12.4.36 and 13.0.0–13.4.17 reduces entropy, allowing attackers to carry out brute‑force attacks more quickly.
Affected versions
Packagist
| Package | Vulnerable | Fixed in |
|---|---|---|
| typo3/cms-core | >= 12.0.0, < 12.4.37 |
12.4.37 |
| typo3/cms-core | >= 13.0.0, < 13.4.18 |
13.4.18 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-331: Insufficient Entropy
The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others.
How to prevent it
- Implementation: Determine the necessary entropy to adequately provide for randomness and predictability. This can be achieved by increasing the number of bits of objects such as keys and seeds.
