SCA: security update for github.com/crossplane/crossplane (GHSA-v829-x6hh-cqfq)

medium Tenable Self-Hosted Container Security Plugin ID 419175

Description

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

 - crossplane-runtime is a set of go libraries used to build Kubernetes controllers in Crossplane and its
 related stacks. In affected versions an already highly privileged user able to create or update
 Compositions can specify an arbitrarily high index in a patch's `ToFieldPath`, which could lead to
 excessive memory usage once such Composition is selected for a Composite resource. Compositions allow
 users to specify patches inserting elements into arrays at an arbitrary index. When a Composition is
 selected for a Composite Resource, patches are evaluated and if a specified index is greater than the
 current size of the target slice, Crossplane will grow that slice up to the specified index, which could
 lead to an excessive amount of memory usage and therefore the Pod being OOM-Killed. The index is already
 capped to the maximum value for a uint32 (4294967295) when parsed, but that is still an unnecessarily
 large value. This issue has been addressed in versions 1.11.2, 1.10.3, and 1.9.2. Users are advised to
 upgrade. Users unable to upgrade can restrict write privileges on Compositions to only admin users as a
 workaround. (CVE-2023-27484)
