In @clerk/hono from versions 0.1.0 to before 0.1.5, @clerk/express from versions 2.0.0 to before 2.0.7, @clerk/backend from versions 3.0.0 to before 3.2.3, and @clerk/fastify from versions 3.1.0 to before 3.1.5, the clerkFrontendApiProxy function in @clerk/backend is vulnerable to Server-Side Request Forgery (SSRF). An unauthenticated attacker can craft a request path that causes the proxy to send the application's Clerk-Secret-Key to an attacker-controlled server. This issue has been patched in @clerk/hono version 0.1.5, @clerk/express version 2.0.7, @clerk/backend version 3.2.3, and @clerk/fastify version 3.1.5.","state":0,"publishedAt":"2026-04-01T16:59:21.828+00:00","modifiedAt":"2026-04-01T18:00:23.118+00:00","affected":[{"ecosystem":"Vendor product","name":"javascript","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"clerk\",\n                    \"product\": \"javascript\",\n                    \"versions\": [\n                        {\n                            \"version\": \"@clerk/hono >= 0.1.0, < 0.1.5\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"@clerk/express >= 2.0.0, < 2.0.7\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"@clerk/backend >= 3.0.0, < 3.2.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"@clerk/fastify >= 3.1.0, < 3.1.5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4,"severity":"HIGH"}],"references":["https://github.com/clerk/javascript/security/advisories/GHSA-gjxx-92w9-8v8f"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-34076","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-34076","identifiers":["CVE-2026-34076"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
