Last modified
CVE-2026-21895 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. The `rsa` crate is an RSA implementation written in rust. Prior to version 0.9.10, when creating a RSA private key from its components, the construction panics instead of returning an error when one of the primes is `1`. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
