What is CVE-2025-4575?

A flaw in the OpenSSL version 3.5 introduces a misconfiguration issue regarding the use of the -addreject option in the x509 command line application. When a user attempts to set a trusted certificate as rejected for certain uses, instead, it is erroneously designated as trusted. This could lead to a trusted CA certificate being recognized for purposes it should not be used for, such as CMS signature verification. Only users utilizing the trusted certificate format with the openssl x509 command are impacted, while earlier OpenSSL versions and FIPS modules remain unaffected.
