Descripción técnica

The Page and Post Restriction plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.6.1 This is due to the `papr_restrict_page_post_rest_api()` function, hooked on `rest_pre_dispatch`, re-authenticating the current user from the `wordpress_logged_in` cookie via `wp_set_current_user()` for any GET or HEAD REST request where the current user is 0, without verifying a REST nonce — silently undoing the nonce-zeroing that WordPress core's `rest_cookie_check_errors()` performs on cookie-authenticated requests that lack an `X-WP-Nonce` header or `_wpnonce` parameter. Combined with WordPress's permissive REST CORS behavior — which echoes the request `Origin` and sets `Access-Control-Allow-Credentials: true` — this allows an unauthenticated attacker to read REST API GET responses as a logged-in victim, exposing role-restricted and private post/page content, victim user profile data via `/wp-json/wp/v2/users/me`, and comments the victim is authorized to see. This requires the attacker to lure a logged-in user into visiting an attacker-controlled page that issues credentialed cross-origin `fetch` requests against the target site's REST API; no nonce or further victim interaction beyond the page visit is needed.

———SOCFortress CoPilot focuses on providing a single pane of glass for all your security operations needs. Prior to 0.1.77, the Velociraptor Sigma exclusion-management endpoints in `backend/app/incidents/routes/incident_alert.py` omit role and tenant authorization, and `POST /api/incidents/alerts/create/velo-sigma/exclusion` does not validate credentials. Its `return_username_for_logging` dependency in `backend/app/auth/utils.py` calls `decode_token`, which returns ordinary Invalid token or Expired signature strings on failure, and the dependency passes these strings through instead of rejecting the request. A Bearer header is required, but an arbitrary invalid, expired or forged value can create a suppression rule without a valid account. The collection GET at /create/velo-sigma/exclusion lists exclusions; the read, update and delete routes under `/create/velo-sigma/exclusion/{exclusion_id}`, and the `/velo-sigma/exclusion/{exclusion_id}/toggle` route, use `get_current_user` without role checks, permitting any authenticated `customer_user` to manage every exclusion. In `backend/app/incidents/services/velo_sigma.py`, `process_sigma_alert` calls `check_exclusions` and drops matching enabled alerts before incident creation. A null `customer_code` applies a rule across all tenants. Attackers can suppress detections platform-wide through channel, title or field matching, while low-privilege accounts can enumerate detection-tuning data and modify, disable or delete legitimate exclusions. This issue is fixed in version 0.1.77.3h CVE-2026-1107999.8 CRÍ

———Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to version 1.0.8.7, the password reset functionality is vulnerable to an Authentication Bypass due to insufficient validation of the user and token GET parameters. This issue has been patched in version 1.0.8.7.4h CVE-2026-1195728.7 ALT

———Traefik from 3.7.0-ea.1 before 3.7.15 contains an authentication bypass vulnerability in the Kubernetes Ingress NGINX provider that silently disables mTLS configured via the auth-tls-secret annotation. When another Ingress declares a path on the same host without matching auth-tls settings, Traefik falls back to default TLS options, letting unauthenticated attackers reach backends requiring client certificates.6h CVE-2026-1144437.5 ALT

——0The Security Plugin, Firewall & Malware Scanner with Auto Removal WordPress plugin before 2.191 does not verify the account password before accepting an authenticator-app two-factor code at login, allowing anyone who holds a user's current authenticator code to log in as that user, including an administrator, without the password.3h CVE-2026-1189595.4 MED

——0A flaw was found in the required action provider mechanism of Keycloak. The issue occurs when an authorization request includes the kc_action query parameter set to a mandatory action already assigned to the user, such as profile verification or terms and conditions. Due to incorrect handling of application-initiated actions, Keycloak may skip these mandatory challenges and issue an authorization code. This can allow a user to bypass administrative requirements and gain access to the application without completing necessary profile updates or agreeing to terms.19h CVE-2026-1070589.8 CRÍ
