FreeScout versions prior to 1.8.235 contain a cross-site scripting (XSS) vulnerability when the APP_CLOUDFLARE_IS_USED setting is enabled. The application trusts the CF-Connecting-IP header during failed login attempts without validation and stores this value in the activity log. The LogsMonitor component inserts this unescaped value into administrator alert emails, allowing injected HTML to execute when the email is viewed. This vulnerability is fixed in version 1.8.235.

FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.224, the FreeScout helpdesk application does not enforce rate limiting on the file upload endpoint. Any user can flood the server with upload requests, leading to database overload and potential denial of service for all users. Version 1.8.224 contains a fix.

FreeScout versions prior to 1.8.224 contain a critical vulnerability in the public user setup endpoint that allows an unauthenticated attacker to overwrite the email and password of the lowest-id activated user account and log in as that user. This occurs due to improper handling of case sensitivity and trailing spaces in the invite_hash field on MySQL/MariaDB, combined with a flawed decryption check that allows bypassing the expiry guard. The vulnerability is fixed in version 1.8.224.

FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. FreeScout's `Manage -> Logs -> App Logs` feature uses the bundled `rap2hpoutre/laravel-log-viewer` override to decrypt a user-supplied file identifier and then pass the resolved path to Laravel's download response. Prior to version 1.8.224, the path resolution logic accepts any existing absolute path before applying the intended `storage/logs` restriction. As a result, an attacker who can access the App Logs route and forge a valid Laravel-encrypted `dl` parameter can download arbitrary server-local files readable by the PHP process, not just log files. Version 1.8.224 contains a fix.

FreeScout versions prior to 1.8.224 have an incomplete denylist for dangerous file uploads, missing the .pht extension. Authenticated users can upload .pht files, which are executed by default Apache PHP handlers, allowing arbitrary command execution as the web server user. This vulnerability is a direct bypass of a previous fix and is addressed in version 1.8.224.

FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.223, an unauthenticated attacker can inject messages into any existing support conversation by sending a single email to the helpdesk's public address with a crafted `In-Reply-To` header. No credentials, tokens, or prior access are required. The injected message is rendered in the agent UI as a legitimate customer reply, the conversation is automatically reopened, and the `last_reply_from` field is set to the attacker's identity. Version 1.8.223 contains a fix.

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.

FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.219, the open tracking endpoint `GET /thread/read/{conversation_id}/{thread_id}` allows unauthenticated attackers to enumerate valid conversation and thread IDs, and modify thread state (`opened_at` timestamp) without any authentication. Version 1.8.219 patches the issue.

FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to 1.8.219, the password reset endpoint returns visually distinct responses depending on whether the submitted email address belongs to an existing user account, allowing unauthenticated attackers to enumerate valid helpdesk agent email addresses. This vulnerability is fixed in 1.8.219.

FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to 1.8.220, the email processing pipeline in FreeScout's FetchEmails command has two code paths for identifying agent (user) replies based on In-Reply-To / References headers. The notification reply path (notify-{thread_id}-{user_id}-...) extracts thread_id and user_id directly from the Message-ID without HMAC verification. An external attacker who can spoof the From address of a helpdesk agent can inject messages that FreeScout processes as legitimate agent replies — which are then automatically forwarded to customers via the legitimate SMTP server. This vulnerability is fixed in 1.8.220.
