Prior to 0.10.11, getActorMCPServerURL in src/mcp/actors.ts concatenates the trusted Actor standby URL with the attacker-controlled webServerMcpPath from an Actor definition without verifying the resulting origin, allowing a malicious Actor publisher to use a userinfo-style authority value to redirect connectMCPClient to a third-party host. The call-actor, fetch-actor-details, and actor-mcp tool-loading paths pass this URL to transports in src/mcp/client.ts that attach the victim Authorization bearer token, exposing the Apify API token and enabling access to Actors, stored data, and billable compute. A victim must invoke or inspect the attacker-controlled Actor. This issue is fixed in version 0.10.11."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"apify","product":"apify-mcp-server","versions":[{"version":"< 0.10.11","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","baseScore":8.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":5.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-08-18T19:30:04.304975Z","id":"CVE-2026-50143","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-918"}]}],"references":[{"url":"https://github.com/apify/apify-mcp-server/commit/ef686d77da3d3c86c30b2ae24218d756aa38e09c","source":"security-advisories@github.com"},{"url":"https://github.com/apify/apify-mcp-server/pull/927","source":"security-advisories@github.com"},{"url":"https://github.com/apify/apify-mcp-server/releases/tag/v0.10.11","source":"security-advisories@github.com"},{"url":"https://github.com/apify/apify-mcp-server/security/advisories/GHSA-6gr2-qh89-hxwm","source":"security-advisories@github.com"},{"url":"https://github.com/apify/apify-mcp-server/security/advisories/GHSA-6gr2-qh89-hxwm","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}}]}
