Summary
The YITH WooCommerce Waitlist Premium plugin for WordPress up to version 3.35.0 is vulnerable to Privilege Escalation. The add_user_in_waiting_list() function lacks capability checks and nonce verification, and uses parse_str() and extract() to import attacker-controlled variables, allowing authenticated attackers with Subscriber-level access to create an administrator account and assign the administrator role.
Risk Assessment
Authenticated attackers with low privileges can gain full control of the site by creating administrator accounts.
Recommendation
Update the plugin to a version newer than 3.35.0 that includes a fix for privilege escalation.

- 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)
The YITH WooCommerce Waitlist Premium plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 3.35.0. This is due to the add_user_in_waiting_list() function registered on the wp_ajax_yith_wcwtl_add_user action being missing both a capability check and a nonce verification, and using parse_str() + extract() to import attacker-controlled variables from $_POST['params'] that are then passed to wp_create_user() and $user->set_role(). This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to that of an administrator by creating a new user account and assigning it the administrator role.
