SCA: security update for openc3 (GHSA-w757-4qv9-mghp)

critical Tenable Self-Hosted Container Security Plugin ID 436712

Description

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

 - OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more
 embedded systems. From 5.0.0 to 6.10.1, OpenC3 COSMOS contains a critical remote code execution
 vulnerability reachable through the JSON-RPC API. When a JSON-RPC request uses the string form of certain
 APIs, attacker-controlled parameter text is parsed into values using String#convert_to_value. For array-
 like inputs, convert_to_value executes eval(). Because the cmd code path parses the command string before
 calling authorize(), an unauthenticated attacker can trigger Ruby code execution even though the request
 ultimately fails authorization (401). This vulnerability is fixed in 6.10.2. (CVE-2025-68271)
