SSRF via set_skywalking_url Tool and GraphQL expression injection vulnerability in Apache SkyWalking MCP. This issue affects Apache SkyWalking MCP: 0.1.0. Users are recommended to upgrade to version 0.2.0, which fixes this issue.
Casky was already ahead
This CVE exploits attack patterns that Casky's 331matched 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.
Apache SkyWalking MCP versions 0.1.0 contain a critical Server-Side Request Forgery (SSRF) vulnerability exploitable through the set_skywalking_url tool, combined with GraphQL expression injection capabilities. With a CVSS score of 9.8, this vulnerability enables attackers to make arbitrary requests from the affected server and inject malicious GraphQL expressions, potentially leading to unauthorized data access, internal network reconnaissance, and system compromise. Organizations deploying SkyWalking MCP for observability and monitoring are directly affected, making immediate patching to version 0.2.0 essential.
Casky's 331 matching security skills leverage Claude's extended reasoning to detect the attack patterns underlying this CVE across MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0006 (Resource Development). Practitioners using Casky will observe findings that correlate suspicious URL parameters passed to skywalking configuration endpoints with CWE-918 SSRF patterns, identify GraphQL query manipulation attempts in request logs, and flag anomalous outbound connections initiated from the SkyWalking service. The platform's skill mapping enables security teams to recognize the reconnaissance phase when attackers probe internal endpoints and the resource development phase where they craft malicious GraphQL payloads, providing contextual detection before exploitation occurs.
