FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.231, the profile form exposes the only_assigned_tickets permission to its non-admin owner, and UsersController::profileSave() adds or removes User::PERM_ONLY_ASSIGNED_TICKETS without checking that the editor is an administrator. A restricted agent can uncheck the option, or submit an ordinary profile save that omits it, to remove the administrator-imposed restriction. The agent can then read and modify conversations assigned to other agents in every mailbox they already belong to. This issue is fixed in version 1.8.231.
In FreedomBox before 26.15, unprivileged user accounts can read/write files for which they lack permissions by setting the authorized_keys file to be a symlink. NOTE: FreedomBox is a Debian Pure Blend, which means that it distributes its software through Debian repositories.
OS command injection in the example SSM document provisioning script in Trusted Remote Execution (REX) before 2026-07-28 might allow an authenticated remote user who is permitted to invoke the Rex-RO or Rex-RW SSM document to execute arbitrary commands as root on the managed instance, bypassing Cedar policy enforcement.
To remediate this issue, users should delete any Rex-RO and Rex-RW SSM documents created from the example script, in each account and Region where it was run.
FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.231, when limit_user_customer_visibility is enabled, the load_customer_info AJAX action performs a global lookup using an attacker-controlled customer email and checks only whether the agent can access a separately supplied mailbox. A non-admin agent can name an accessible mailbox and retrieve an unrelated customer's rendered profile without invoking CustomerPolicy::view(). The response can expose names, email addresses, phone numbers, company and job information, postal addresses, social profiles, websites, and confidential internal agent notes. This issue is fixed in version 1.8.231.
FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.230, multiple outbound paths in Helper::downloadRemoteFile(), Helper::checkPort(), Helper::sanitizeRemoteUrl(), MailboxesController.php, and ModulesController.php do not consistently enforce a sink-level restricted-host policy. An authenticated administrator, or another authenticated user permitted to change mailbox connection settings or trigger module update or installation paths, can supply attacker-controlled URLs or hosts. The independent download and port-test sinks can reach encoded or otherwise uncovered loopback and internal addresses. The redirect-validation bypass additionally requires a configured whitelist that permits the original and final hosts while a restricted internal host appears only as an intermediate redirect hop. No unauthenticated SSRF path is established. The server can consequently contact loopback and internal services, provide a blind internal port oracle, and retrieve internal HTTP responses into application-controlled download sinks. This issue is fixed in version 1.8.230.
FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.227, the conversation_merge action records a failed authorization check for the target conversation in response['msg'] and then clears that value inside the source-conversation loop. An authenticated agent can merge a conversation they control into a target conversation in a mailbox they cannot access. The operation injects threads, attachments, and audit records into the unauthorized target and deletes the source conversation, but it does not disclose the target's existing contents. This issue is fixed in version 1.8.227.
FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.225, the administrative tools.php maintenance endpoint is reachable without an appropriate authentication or access-control boundary. Response differences for attacker-controlled path values disclose whether arbitrary directories and files exist on the server. The same endpoint validates application-key and database-password candidates without rate limiting, per-session throttling, or a CAPTCHA, allowing unrestricted guessing attempts against application secrets. This issue is fixed in version 1.8.225.
FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.226, RealtimeConvNewThread checks only general mailbox access and does not apply the conversation-level restriction for users configured to see only assigned conversations. A restricted authenticated user can subscribe to predictable conv.<conversation_id> Polycast channels for other conversations in the same mailbox. New event payloads can expose complete replies, internal notes, recipient addresses, conversation state, assignee data, attachment names, and attachment URLs containing valid download tokens. This issue is fixed in version 1.8.226.
FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.225, the administrator-only App Logs viewer accepts Laravel-encrypted folder and file parameters whose constructed path is checked only as a raw string. An administrator who also knows the APP_KEY can supply traversal segments that the filesystem normalizes outside storage/logs. The /app-logs/app route can then read local files accessible to the PHP worker, including environment files, source files, credentials, tokens, and operating-system files. This issue is fixed in version 1.8.225.
Prototype Pollution in @progress/kendo-vue-common in Progress Software Kendo UI for Vue versions 0.4.0 through 9.2.0 allows a high-privileged attacker who can control a field path processed by components such as the Scheduler to modify the prototype of built-in objects, resulting in a limited impact on confidentiality, integrity, and availability.
FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.226, the search-by-number shortcut in ConversationsController::search() resolves a user-controlled ticket number without applying the mailbox filter or view policy used by the normal search path. An authenticated non-admin agent who is a member of at least one mailbox can request /search with a hash-prefixed ticket number and use the 302 Location header to confirm that a conversation exists in a different mailbox the agent cannot access and learn its internal conversation and folder identifiers. The destination conversation remains protected, so this issue does not disclose message content, attachments, or customer data. This issue is fixed in version 1.8.226.
Prototype Pollution in the setter utility (@progress/kendo-react-common) in Progress Software KendoReact versions 3.5.0 through 16.0.0 allows a high-privileged attacker who can control a field path passed to the utility, directly or through components such as the Form, Scheduler, and Gantt, to modify the prototype of built-in objects, resulting in a limited impact on confidentiality, integrity, and availability.
FreeScout versions prior to 1.8.226 contain a SQL injection vulnerability in the polycast/receive endpoint. This flaw allows an unauthenticated attacker with a guest session and valid CSRF token to submit specially crafted wildcard channel names, bypassing channel authorization checks. As a result, the attacker can retrieve notification events and associated conversation message content, identifiers, URLs, and notification HTML intended for other users. The issue is resolved in version 1.8.226.
Prototype Pollution in the Scheduler component (@progress/kendo-angular-scheduler and @progress/kendo-angular-common) in Progress Software Kendo UI for Angular versions prior to 25.1.0 allows a high-privileged attacker who can control a field path processed by the Scheduler to modify the prototype of built-in objects, resulting in a limited impact on confidentiality, integrity, and availability.
Cross-Site Scripting (XSS) in the Editor component (@progress/kendo-vue-editor) in Progress Software Kendo UI for Vue versions 2.7.1 through 10.0.0 allows a low-privileged attacker who can supply Editor content to execute arbitrary JavaScript in another user's browser via an unsafe URL entered in the Insert Link or Insert Image dialog, which runs when the user clicks the resulting link.
Cross-Site Scripting (XSS) in the Editor component (@progress/kendo-react-editor) in Progress Software KendoReact versions 2.7.0 through 16.1.0 allows a low-privileged attacker who can supply Editor content to execute arbitrary JavaScript in another user's browser via a link with an unsafe URL in the Editor content, which runs when the user clicks the link.
Cross-Site Scripting (XSS) in the Editor component (@progress/kendo-angular-editor) in Progress Software Kendo UI for Angular versions prior to 25.3.0 allows a low-privileged attacker who can supply Editor content to execute arbitrary JavaScript in another user's browser via a link or image with an unsafe URL in the Editor content, which runs when the user interacts with it.
Cross-Site Scripting (XSS) in the Chat component (@progress/kendo-react-conversational-ui) in Progress Software KendoReact versions 0.6.0 through 16.1.0 allows a low-privileged attacker who can supply Chat messages to execute arbitrary JavaScript in the origin of the application via an unsafe URL in an openUrl quick action, which runs when a user clicks the action.
CVE-2026-62854 is a cross-site scripting (XSS) vulnerability in FreeScout versions prior to 1.8.225. It allows a user with permission to edit mailbox signatures to inject scriptable content by combining uploaded files and nested tag fragments that bypass sanitization. The malicious script executes with the victim's privileges when they open the mailbox reply editor or new-ticket page. This vulnerability is fixed in FreeScout version 1.8.225.
Cross-Site Scripting (XSS) in the Menu component (@progress/kendo-react-layout) in Progress Software KendoReact versions 1.3.0 through 16.1.0 allows a low-privileged attacker who can influence the Menu item data to execute arbitrary JavaScript in the origin of the application via an unsafe URL in a Menu item, which runs when a user selects the item.
