Summary
Alchemy CMS before versions 7.4.15, 8.0.15, 8.1.14, and 8.2.6 exposes an unauthenticated GET /api/pages/nested endpoint that returns an unfiltered page tree without authorization. Restricted and unpublished page metadata and element/ingredient content can be retrieved.
Risk Assessment
The risk includes unauthorized access to sensitive page metadata and content, potentially compromising data confidentiality and content management integrity.
Recommendation
Upgrade Alchemy to one of the fixed versions (7.4.15, 8.0.15, 8.1.14, or 8.2.6) and enforce access controls at the API level.

- CVE-2026-61567Critical
In AVideo before 8.1.0, the live-streaming endpoint `view/videosListToLive.php` trusts attacker-supplied data in `webSiteRootURL` as session state, allowing an unauthenticated attacker to self-grant `isLogged` and `canStream`. Video-list paths are interpolated without escaping into `ffprobe` and `ffmpeg` commands executed via `exec`, enabling OS command injection. This is fixed in version 8.1.0.
- CVE-2026-61564Critical
In AVideo before 8.1.0, the unauthenticated installer endpoint `install/checkConfiguration.php` assembles `videos/configuration.php` by interpolating request parameters, including `webSiteRootURL`, into single-quoted PHP literals without escaping. An attacker can terminate a literal and inject PHP executed as the web-server user. Exploitation requires `videos/configuration.php` to be absent, and database parameters can point to an attacker-controlled server. This is fixed in version 8.1.0.
- CVE-2026-118690Critical
Signal K Server before 2.33.0 contains a missing authentication vulnerability that allows unauthenticated remote attackers to download log archives via the `/skServer/ziplogs` endpoint. Attackers can extract the JWT `secretKey` from `security.json` in the ZIP, forge administrator tokens, and create persistent admin accounts. This is fixed in version 2.33.0.
- CVE-2026-63190Critical
Prior to version 0.1.4, FearlessCMS contains five debug/test PHP scripts under admin/ that perform privileged operations without authentication, CSRF protection, or adequate path validation. On PHP's built-in server (including the default Docker deployment), the /./admin/ path bypasses the login gate, enabling arbitrary .md writes, directory enumeration, stored/reflected XSS, and disk exhaustion.
- CVE-2026-117574Critical
In ai-gateway-payload-processing, an authenticated remote attacker can specify another tenant's model identifier in the request body or header. The service does not verify authorization before retrieving credentials from the shared store, so it injects the target tenant's API keys into the request.
- CVE-2026-118264Critical
In the Echo Go web framework from 4.0.0 until 4.16.1 and in 5.4.1, the Proxy middleware selects a raw tunnel from a client WebSocket upgrade request before verifying that the configured upstream accepted the upgrade. If the upstream rejects the upgrade with an ordinary keep-alive response, later HTTP requests on the connection are sent directly to that upstream, bypassing Echo's router and route-specific middleware. This can bypass authentication or authorization enforced only by Echo routes.
- CVE-2026-103409Critical
A missing authentication for a critical function vulnerability in Juniper Networks Session Smart Router allows an unauthenticated network-based attacker to obtain administrative privileges by passing crafted URL parameters to an insecure endpoint running as root. The vulnerability can only be exploited prior to the device being onboarded to Mist/Conductor; it can no longer be exploited once the device is onboarded.
- CVE-2026-103406Critical
An improper neutralization of special elements used in an OS command vulnerability in the AutomatedProvisioner in Juniper Networks Session Smart Conductor allows a remote attacker to execute arbitrary commands as root via a specially crafted salt minion ID.
- CVE-2026-44179Critical
The `excerpt-include` macro in XWiki Remote Macros does not properly escape the included page's title and executes `excerpt` content with the macro's rights. Both the title handling and the rendering of `excerpt` content into XWiki syntax allow syntax injection. Any user able to edit a page, even without script rights, can supply executable macro syntax and cause remote code execution when the page is included.
- CVE-2026-115968Critical
A deserialization of untrusted data vulnerability in the Ultimate Member WordPress plugin allows Object Injection. Affects versions up to and including 2.13.1.
Original NVD description (English source)
Alchemy is an open source content management system engine written in Ruby on Rails. Prior to 7.4.15, 8.0.15, 8.1.14, and 8.2.6, the unauthenticated GET /api/pages/nested endpoint implemented by Api::PagesController#nested in app/controllers/alchemy/api/pages_controller.rb returns an unfiltered page tree because it performs no authorization and does not scope descendants by the caller's ability. Anonymous callers can retrieve restricted and unpublished page metadata that the sibling show action denies. When elements=true is supplied, PageTreeSerializer also returns element and ingredient content from restricted pages because PageTreePreloader and the serializer do not apply an ability check to those records. This issue is fixed in versions 7.4.15, 8.0.15, 8.1.14, and 8.2.6.
