CVE-2021-31798
The effective key space used to encrypt the cache in CyberArk Credential Provider prior to 12.1 has low entropy, and under certain conditions a local malicious user can obtain the plaintext of cache files.
Does this matter?
Lower severity and a low EPSS score (0.44%). Track it; it rarely justifies an emergency change on its own.
