Hi,

The following vulnerability was published for cryptojs.

CVE-2023-46233[0]:
| crypto-js is a JavaScript library of crypto standards. Prior to
| version 4.2.0, crypto-js PBKDF2 is 1,000 times weaker than
| originally specified in 1993, and at least 1,300,000 times weaker
| than current industry standard. This is because it both defaults to
| SHA1, a cryptographic hash algorithm considered insecure since at
| least 2005, and defaults to one single iteration, a 'strength' or
| 'difficulty' value specified at 1,000 when specified in 1993. PBKDF2
| relies on iteration count as a countermeasure to preimage and
| collision attacks. If used to protect passwords, the impact is high.
| If used to generate signatures, the impact is high. Version 4.2.0
| contains a patch for this issue. As a workaround, configure crypto-
| js to use SHA256 with at least 250,000 iterations.


If you fix the vulnerability please also make sure to include the
