Prior to 2.9.14, Turborepo's self-hosted login and SSO browser flows did not validate a CSRF state value on the localhost callback. While the CLI was waiting for authentication, a malicious web page could send a request to the local callback server with an attacker-controlled token. If accepted before the legitimate callback, the CLI could complete login with the wrong credentials. This affects users authenticating the turbo CLI against self-hosted remote cache/auth endpoints. Vercel-hosted login flows using device authorization are not affected. This vulnerability is fixed in 2.9.14.","state":0,"publishedAt":"2026-05-15T15:51:38.066+00:00","modifiedAt":"2026-05-15T16:45:06.076+00:00","affected":[{"ecosystem":"Vendor product","name":"turborepo","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"vercel\",\n                    \"product\": \"turborepo\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.9.14\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:L/VA:N/SC:L/SI:H/SA:N","score":5.1,"severity":"MEDIUM"}],"references":["https://github.com/vercel/turborepo/security/advisories/GHSA-hcf7-66rw-9f5r"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-45773","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-45773","identifiers":["CVE-2026-45773"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
