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."}],"source":{"advisory":"GHSA-6gcm-v8xf-j9v9","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/freescout-help-desk/freescout/security/advisories/GHSA-6gcm-v8xf-j9v9","tags":["exploit"]},{"url":"https://github.com/freescout-help-desk/freescout/security/advisories/GHSA-mw88-x7j3-74vc","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-02-25T15:21:46.046132Z","id":"CVE-2026-27637","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-02-25T15:21:52.817Z"}}]}}
