Alert meAnalysisAIv1 – Mar 12, 2026
Tool name collision in WeKnora's MCP client integration allows remote attackers with network access to register malicious tools that overwrite legitimate ones, enabling prompt injection attacks and potential data exfiltration. An attacker exploiting this vulnerability can redirect LLM execution to steal system prompts and context data, or execute arbitrary tools with the privileges of authenticated users. This affects WeKnora versions prior to 0.3.0.

This vulnerability (CWE-706: Use of Incorrectly-Resolved Name or Reference) affects WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval.. 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).

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.
Executive ViewAI
Organizations using WeKnora should be aware of moderate risk from CVE-2026-30856 rated CVSS 5.9. Exploitation could compromise the security of affected deployments. Organizations should apply vendor updates when available and monitor for exploitation.
Apply vendor patch. If patching is delayed: restrict network access and enable monitoring.
