CVE-2025-4575 is a low-severity vulnerability in OpenSSL 3.5 where the openssl x509 command-line application incorrectly adds a trusted use instead of a rejected use for a certificate when the -addreject option is employed. This could lead to a certificate being trusted for purposes it was intended to be rejected for, such as CMS signature verification. The CVSS score is 6.5 (MEDIUM), indicating a network-based attack with low impact on integrity and availability. There is currently no known active exploitation, public exploit code, or significant community discussion, and it is not listed in the KEV catalog.
