A vulnerability exists in the Kong Konnect Model Context Protocol (MCP) server prior to version 1.0.0, which could allow a remote attacker to perform an indirect prompt injection attack and execute unintended API requests.
Casky was already ahead
This CVE exploits attack patterns that Casky's 322matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.
CVE-2026-13341 represents a high-severity indirect prompt injection vulnerability affecting Kong Konnect's Model Context Protocol server versions prior to 1.0.0. This vulnerability allows remote attackers to manipulate AI model inputs through compromised or untrusted data sources, causing Claude or other LLM instances to execute unintended API requests on behalf of the Kong infrastructure. Organizations deploying Kong Konnect for API management, particularly those integrating MCP servers for enhanced AI-driven capabilities, face immediate risk of unauthorized API operations, data exfiltration, and lateral movement within their infrastructure. The vulnerability is especially critical because it exploits the trust relationship between AI models and backend systems, making detection difficult without proper input validation and output verification controls.
Casky's 322 matching skills leverage Claude's extended reasoning capabilities to detect the attack patterns behind this CVE by correlating behaviors across MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance via resource development). Practitioners using Casky would identify suspicious patterns including: anomalous prompt structures attempting to override system instructions, unexpected API request chains originating from MCP server contexts, and deviations in request signatures typical of indirect injection attacks. The platform's skills would surface findings showing how attackers probe Kong Konnect endpoints for MCP integration points, analyze response patterns to infer backend API structures, and craft multi-stage prompts designed to bypass input sanitization. Security teams would receive alerts highlighting malformed or instruction-override attempts in model inputs, unusual API calls executed through the MCP server, and evidence of reconnaissance activities mapping Kong's API topology—enabling rapid containment before privilege escalation or data theft occurs.
