Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
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.

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to the setSigningKey
method within the DefaultJwtParser
class and the signWith
method within the DefaultJwtBuilder
class. A user can falsely conclude that their key is strong while in reality it is weak due to DatatypeConverter.parseBase64Binary()
method removing certain special characters. An attacker could easier crack a user's key that is considered strong by using brute force.
