Overview
Affected versions of this package are vulnerable to Resource Exhaustion by processing JSON Web Encryption (JWE) tokens with a high compression ratio. An attacker can cause excessive memory allocation and processing time during decompression, leading to a denial-of-service condition. This is only exploitable if the attacker has access to the public encrypt key registered with the IDP (Entra ID).
