SCA: security update for org.pac4j:pac4j-oidc (GHSA-xhw6-hjc9-679m)

high Tenable Cloud Security Plugin ID 420536

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - If an OpenID Connect provider supports the "none" algorithm (i.e., tokens with no signature), pac4j v5.3.0
 (and prior) does not refuse it without an explicit configuration on its side or for the "idtoken" response
 type which is not secure and violates the OpenID Core Specification. The "none" algorithm does not require
 any signature verification when validating the ID tokens, which allows the attacker to bypass the token
 validation by injecting a malformed ID token using "none" as the value of "alg" key in the header with an
 empty signature value. (CVE-2021-44878)
