CVE-2010-4334
The IO::Socket::SSL module 1.35 for Perl, when verify_mode is not VERIFY_NONE, fails open to VERIFY_NONE instead of throwing an error when a ca_file/ca_path cannot be verified, which allows remote attackers to bypass intended certificate restrictions.

Does this matter?
Lower severity and a low EPSS score (1.78%). Track it; it rarely justifies an emergency change on its own.
