DescriptionCVE.org

FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.221, FreeScout's attachment download route skips token authentication for any attachment whose token_type is set to 1 (TOKEN_TYPE_LEGACY). Because this route is unauthenticated and the file path is deterministic, an unauthenticated remote attacker can download any attachment that was created by an older version of FreeScout without possessing a valid token or session. Version 1.8.221 contains a fix.

AnalysisAI

Broken authentication in FreeScout (a PHP/Laravel self-hosted help desk and shared inbox) prior to version 1.8.221 lets an unauthenticated remote attacker download arbitrary attachments whose token_type is set to 1 (TOKEN_TYPE_LEGACY). The download route bypasses token verification for these legacy attachments, and because file paths are deterministic, any attachment created by an older FreeScout instance can be retrieved without a valid token or session. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires that the target attachment was created by an older FreeScout version and therefore carries token_type = 1 (TOKEN_TYPE_LEGACY); attachments without this legacy type still enforce token validation and are not exposed. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, score 7.5) is internally consistent with the description: network-reachable, low complexity, no privileges, no user interaction, high confidentiality impact and no integrity/availability impact - a pure unauthenticated information-disclosure flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker who knows or can enumerate the deterministic storage path structure sends an unauthenticated HTTP GET to the FreeScout attachment download route for a legacy (token_type=1) file, omitting or supplying any token value. Because the server skips token validation for legacy attachments, it returns the file - potentially confidential support-ticket contents such as invoices, PII, credentials, or internal documents. …
Remediation	Vendor-released patch: upgrade FreeScout to version 1.8.221 or later, which removes the TOKEN_TYPE_LEGACY exemption so every attachment download requires a matching content-hash token (see the advisory at https://github.com/freescout-help-desk/freescout/security/advisories/GHSA-wg74-ww4w-2qpc and fix commit https://github.com/freescout-help-desk/freescout/commit/215241ee2eb73eaa3b47e392599c7dc1b427dc7e). … Detailed patch versions, workarounds, and compensating controls in full report.
