SCA: security update for openclaude (GHSA-m77w-p5jj-xmhg)

critical Tenable Self-Hosted Container Security Plugin ID 442251

Description

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

 - OpenClaude is an open-source coding-agent command line interface for cloud and local model providers.
 Prior to version 0.5.1, the dangerouslyDisableSandbox parameter is exposed as part of the BashTool input
 schema, meaning the LLM (an untrusted principal per the project's own threat model) can set it to true in
 any tool_use response. Combined with the default allowUnsandboxedCommands: true setting, a prompt-injected
 model can escape the sandbox for any arbitrary command, achieving full host-level code execution. This
 issue has been patched in version 0.5.1. (CVE-2026-42074)

Solution

Update the openclaude library and its related packages to version 0.5.1 or later.
