Last modified Jun 17, 2026

CVE-2025-58187 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary certificate chains.. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
