CVE-2026-55454

ZITADEL before 3.4.14 and 4.x before 4.16.2 contains an authentication bypass in the hosted Login V1 UI because the 'external account not found' registration endpoint trusts client-supplied external identity fields without a completed IdP callback. Unauthenticated attackers can submit forged IDPConfigID and ExternalUserID values to pre-create an account bound to a victim's external IdP identity, which the victim's later genuine external login then signs into.

ZITADEL 3.x before 3.4.15 and 4.x before 4.17.1 contains an improper authorization vulnerability: when issuing passkey or passwordless enrollment codes, it checks only the organization in the x-zitadel-orgid header, not the target user's organization. Attackers with user-write permission in one organization can obtain an enrollment code for a user in another organization on the same instance and register their own authenticator to take over that account.

ZITADEL 3.0.0 through 3.4.15 and 4.0.0 before 4.17.3 creates links between user accounts and external identity providers without verifying a primary factor or the caller's permission, including on identify-only Login V2 sessions and via the User Service V2 AddIDPLink endpoint. An unauthenticated attacker knowing a victim's login name can bind their own external IdP identity to the victim's account and then sign in as the victim.

The Unlimited Elements For Elementor plugin up to version 2.0.20 contains a blind SQL injection vulnerability. An attacker can exploit this flaw to manipulate database queries without knowing the database structure.

A code injection vulnerability was found in InternLM MindSearch 0.1.0 in the ExecutionAction.run function in mindsearch/agent/graph.py. The attack can be launched remotely, and exploit details have been publicly disclosed.

An OS command injection vulnerability was found in AhsayCBS up to version 10.3.2 in the file /rps/api/json/UpdateReceivers.do. The attack can be launched remotely, and the exploit has been published. Upgrading to version 10.3.4 resolves the issue.

Missing authentication for critical function in the ait-server telemetry and command broker in NASA-AMMOS AIT-Core through 3.1.1. An unauthenticated remote attacker with network access to the ZeroMQ message bus can inject spacecraft command data, exfiltrate command and telemetry traffic, inject forged telemetry, or disrupt the bus. The ZeroMQ broker binds XSUB and XPUB sockets to all interfaces by default without authentication.

In Bouncy Castle for Java before 1.86, the Messaging Layer Security (MLS, RFC 9420) implementation did not bind an X.509 credential to a LeafNode's signature_key. LeafNode.verify() checked a leaf's signature against the signature_key carried in the leaf itself, while the credential's X.509 certificate chain was stored but never parsed or validated, so the end-entity certificate's public key was never required to match signature_key as RFC 9420 sec. 5.3 requires. An attacker could present another party's certificate as its credential while signing the leaf, and the enclosing KeyPackage, with an unrelated key, and be accepted under that other party's identity through KeyPackage.verify() and the Group leaf-validation path.

The Beaver Builder Page Builder plugin for WordPress up to version 2.11.0.5 is vulnerable to arbitrary shortcode execution. This is due to insufficient validation before running do_shortcode, allowing unauthenticated attackers to execute arbitrary shortcodes. Exploitation requires a page with the Sidebar module containing a widget that displays attacker-controlled text, such as the Recent Comments widget with approved comments.
