SCA: security update for github.com/Tencent/WeKnora (GHSA-67q9-58vj-32qx)

high Tenable Cloud Security Plugin ID 438516

Description

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

 - WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior
 to version 0.3.0, a vulnerability involving tool name collision and indirect prompt injection allows a
 malicious remote MCP server to hijack tool execution. By exploiting an ambiguous naming convention in the
 MCP client (mcp_{service}_{tool}), an attacker can register a malicious tool that overwrites a legitimate
 one (e.g., tavily_extract). This enables the attacker to redirect LLM execution flow, exfiltrate system
 prompts, context, and potentially execute other tools with the user's privileges. This issue has been
 patched in version 0.3.0. (CVE-2026-30856)

Solution

Update the github.com/Tencent/WeKnora library and its related packages to version 0.3.0 or later.
