fix: Medium Vulnerability in validator@13.15.15 (CVE-2025-56200)

[SchroederSteffen]

Description

See validatorjs/validator.js#2600.

Expected behavior

They are still working on a fix, but as soon as it's available, I'd like to request raising the minimum validator version for class-validator to include the fix automatically.

Is there an estimation for the fix ?

Just created a PR #2638 for review. It's my first time creating a PR in this repo, feel free to let me know if I need to change anything. Thanks!
