From 1.1.0 to 1.7.4, the TrailingSlashMiddleware in internal/api/server.go is vulnerable to an open redirect attack. An attacker can craft a URL with a protocol-relative path (e.g., //evil.com/) that, after trailing slash removal, results in a Location header of //evil.com — which browsers interpret as an absolute URL to an external domain. This vulnerability is fixed in 1.7.5.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[],"references":["https://github.com/modelcontextprotocol/registry/security/advisories/GHSA-v8vw-gw5j-w7m6"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-30491","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"May 14, 2026, 9:07:34 PM","dateUpdated":"May 15, 2026, 1:33:16 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
