dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, the application accepts unlimited password guesses against both the browser login flow and the JSON login endpoint. The source code enables Devise's `:lockable` module on the user model but explicitly disables both lock and unlock strategies, and no request throttling or rate-limiting layer was identified in the Rails code. This creates a direct online password-guessing risk:
- valid user accounts can be attacked continuously without temporary lockout
- the same weakness is reachable through both `/users/sign_in` and `/api/v4/auth/login`
- successful guessing yields a normal session cookie in the HTML flow or a fresh JWT in the API flow
- the API endpoint is especially attractive for automation because it requires no CSRF token
This has been patched in version 26.06.08.
dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, a low-privileged authenticated API user can supply `forwardToUrl` and `redirectUrl` values when triggering password reset or confirmation flows. Those values are then embedded into the outgoing email workflow without host allowlisting. This creates two related abuse paths:
- password reset or confirmation links can be sent to a victim with the token already attached to an attacker-controlled `forwardToUrl`
- after a legitimate password reset completes, the browser is redirected to attacker-controlled `redirectUrl`
In practice, this can be used for phishing, token capture, confirmation hijacking, or steering a victim from a trusted email
into an attacker domain. This is patched in version 26.06.08.
dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, the application exposes server-side state changes through `GET` routes. Because browsers automatically send cookies on same-site top-level navigation and Rails does not apply CSRF protections to `GET`, an attacker can force a logged-in victim to modify application state by embedding a link, image, iframe, or redirect to one of these endpoints. This was confirmed on the target with a normal `Standard` account: a cross-site-style `GET` to `watch_lists/:id/add_item?thing_id=...` inserted content into a watch list with no CSRF token. Additional `GET` mutation routes exist in the codebase, including user impersonation for authorized admins and cache or
translation state changes. This is patched in version 26.06.08.
dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, any authenticated API user who has their own access token can ask the collection API to evaluate permissions as a different user by supplying `user_email`. If the target user has collections, this can expose those collections through the API. In V4, once a collection id is known, the same controller also offers `add_item` and `remove_item` routes without any object-level `authorize!` checks,
creating a likely cross-user modification path. This is patched in version 26.06.08.
dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, any authenticated user can request arbitrary partials or helper-backed render functions through /remote_render. The endpoint does not restrict which partial can be rendered and does not apply controller-specific authorization before rendering the selected view. This enables a low-privileged user to retrieve server-side rendered admin content that is otherwise hidden by navigation and route checks. On the test instance, a Standard user was able to retrieve the PostgreSQL admin dashboard stats even though /admin itself redirected away. This is patched in 26.06.08.
A path traversal vulnerability exists in dataCycle-CORE, a module of the dataCycle data management system, in versions up to and including 25.07.3. The vulnerability allows an unauthenticated attacker to traverse outside intended directories and render arbitrary markdown (.md) files from the application or engine root. This occurs because the input path segments are only sanitized with a Rails HTML sanitizer, which does not remove directory traversal sequences. The issue is fixed in version 26.06.08.
dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, a Standard user can enumerate other users' names and email addresses through `/users/search`, even though direct access to those user profiles is denied. This leaks internal staff addresses, full names, and existence of guest and external test accounts.
dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, any unauthenticated attacker can place arbitrary HTML into flash notifications on public routes and rely on the frontend toast component to inject that content into the DOM with `innerHTML`. This creates a reflected DOM XSS that can be delivered with a crafted link to a public page such as `/docs`. Because the vulnerable JavaScript is loaded by the normal application layout, the issue is not limited to a special debug page or an isolated admin-only view.
dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, anyone with a DataLink UUID can fetch the attached text file directly, even if the link is expired, the caller is unauthenticated, or the normal show flow would have denied access. Because the route is public and the mailer embeds the direct file URL, any leaked, forwarded, logged, or stale email link can continue to expose the attachment.
