SCA: security update for github.com/kyverno/kyverno (GHSA-r5p3-955p-5ggq)
high Tenable Self-Hosted Container Security Plugin ID 428610
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Kyverno is a policy engine designed for cloud native platform engineering teams. In versions 1.14.1 and
below, a Denial of Service (DoS) vulnerability exists due to improper handling of JMESPath variable
substitutions. Attackers with permissions to create or update Kyverno policies can craft expressions using
the {{@}} variable combined with a pipe and an invalid JMESPath function (e.g., {{@ |
non_existent_function }}). This leads to a nil value being substituted into the policy structure.
Subsequent processing by internal functions, specifically getValueAsStringMap, which expect string values,
results in a panic due to a type assertion failure (interface {} is nil, not string). This crashes Kyverno
worker threads in the admission controller and causes continuous crashes of the reports controller pod.
This is fixed in version 1.14.2. (CVE-2025-47281)
