Inefficient Algorithmic Complexity Affecting github.com/go-jose/go-jose/v4 package, versions <4.1.6
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Upgrade github.com/go-jose/go-jose/v4 to version 4.1.6 or higher.
Overview
Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity in the parsing process of JWKs containing RSA keys due to lack of size and consistency checks on RSA modulus and prime values before validation. An attacker can cause excessive CPU consumption and disrupt service availability by submitting specially crafted JWKs with large or malformed RSA parameters.
