SCA: security update for jsonata (GHSA-66mm-25pp-rfff)

critical Tenable Self-Hosted Container Security Plugin ID 446229

Description

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

 - JSONata is a JSON query and transformation language. Prior to 1.8.8 and 2.2.1, crafted JSONata expressions
 could chain several object-integrity weaknesses to execute arbitrary code. The chain could overwrite
 $clone to mutate objects through evaluateTransformExpression, expose and deconstruct JSONata functions or
 lambdas through $merge.*, replace proc.arguments.forEach used by applyProcedure, and forge internal lambda
 state. These primitives allowed an attacker to reach prototype getters, prototype and constructor access,
 and process.getBuiltinModule with child_process, executing code with the privileges of the host process.
 This issue is fixed in versions 1.8.8 and 2.2.1. (CVE-2026-77415)

Solution

Update the jsonata library and its related packages to version 1.8.8 or later.
