MEDIUMPre-NVD 5.35.3—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 84% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Activepieces is an open source AI workflow automation platform. Prior to 0.82.0, the POST /api/v1/projects/:projectId/mcp-server/validate-agent-mcp-tool endpoint makes an outbound HTTP or SSE request to a user-supplied serverUrl without URL validation or SSRF protection. An authenticated user can cause the Activepieces server to connect to internal services, cloud metadata endpoints, or arbitrary external hosts and probe network reachability from the Activepieces host. This issue is fixed in version 0.82.0.
