Prior to version 1.8.206, FreeScout's file upload restriction list in `app/Misc/Helper.php` does not include `.htaccess` or `.user.ini` files. On Apache servers with `AllowOverride All` (a common configuration), an authenticated user can upload a `.htaccess` file to redefine how files are processed, enabling Remote Code Execution. This vulnerability can be exploited on its own or in combination with CVE-2026-27637. Version 1.8.206 fixes both vulnerabilities.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-434"],"references":["https://github.com/freescout-help-desk/freescout/commit/9984071e6f1b4e633fdcffcea82bbebc9c1e009c","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-2026-27636","score":0.02218,"percentile":0.82661,"date":"2026-10-31"},"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).
