{"cve":"CVE-2026-45773","nvd":{"published":"2026-05-15T16:16:15.137","modified":"2026-10-26T14:10:00.130","status":"Analyzed","description":"Turborepo is a high-performance build system for JavaScript and TypeScript codebases. 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.","cvss_v4":{"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},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-352","CWE-384"],"references":["https://github.com/vercel/turborepo/security/advisories/GHSA-hcf7-66rw-9f5r"],"products":["vercel:turborepo"],"source":"nvd","synced_at":"2026-10-26T14:27:29.784594657+00:00"},"epss":{"cve":"CVE-2026-45773","score":0.00124,"percentile":0.02151,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-hcf7-66rw-9f5r","url":"https://osv.dev/vulnerability/GHSA-hcf7-66rw-9f5r","summary":"Turbo: Login callback CSRF/session fixation","modified":"2026-09-10T03:50:47.005813526Z","packages":[{"ecosystem":"npm","name":"turbo","purl":"pkg:npm/turbo","ranges":["<2.9.14"],"fixed":["2.9.14"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
