SCA: security update for io.ratpack:ratpack-core (GHSA-hc33-32vw-rpp9)

high Tenable Self-Hosted Container Security Plugin ID 415630

Description

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

 - Ratpack is a toolkit for creating web applications. In versions prior to 1.9.0, a malicious attacker can
 achieve Remote Code Execution (RCE) via a maliciously crafted Java deserialization gadget chain leveraged
 against the Ratpack session store. If one's application does not use Ratpack's session mechanism, it is
 not vulnerable. Ratpack 1.9.0 introduces a strict allow-list mechanism that mitigates this vulnerability
 when used. Two possible workarounds exist. The simplest mitigation for users of earlier versions is to
 reduce the likelihood of attackers being able to write to the session data store. Alternatively or
 additionally, the allow-list mechanism could be manually back ported by providing an alternative
 implementation of `SessionSerializer` that uses an allow-list. (CVE-2021-29485)
