{"cve":"CVE-2026-27637","nvd":{"published":"2026-02-25T04:16:04.110","modified":"2026-06-17T10:27:26.093","status":"Analyzed","description":"FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.206, FreeScout's `TokenAuth` middleware uses a predictable authentication token computed as `MD5(user_id + created_at + APP_KEY)`. This token is static (never expires/rotates), and if an attacker obtains the `APP_KEY` — a well-documented and common exposure vector in Laravel applications — they can compute a valid token for any user, including the administrator, achieving full account takeover without any password. This vulnerability can be exploited on its own or in combination with CVE-2026-27636. Version 1.8.206 fixes both vulnerabilities.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-330"],"references":["https://github.com/freescout-help-desk/freescout/commit/004a8231f6e413af1d4680930b0e2342fd4283f9","https://github.com/freescout-help-desk/freescout/security/advisories/GHSA-6gcm-v8xf-j9v9","https://github.com/freescout-help-desk/freescout/security/advisories/GHSA-mw88-x7j3-74vc","https://github.com/freescout-help-desk/freescout/security/advisories/GHSA-6gcm-v8xf-j9v9","https://github.com/freescout-help-desk/freescout/security/advisories/GHSA-mw88-x7j3-74vc"],"products":["freescout:freescout"],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-27637","score":0.0076,"percentile":0.55298,"date":"2026-11-01"},"kev":null,"osv":[],"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).
