Last modified
CVE-2021-37606 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. Meow hash 0.5/calico does not sufficiently thwart key recovery by an attacker who can query whether there's a collision in the bottom bits of the hashes of two messages, as demonstrated by an attack against a long-running web service that allows the attacker to infer collisions by measuring timing differences.. EPSS estimates a 0.74% chance of exploitation in the next 30 days.
