CVE-2026-90456

GetSimple CMS (v3.4.0a and below) and GetSimple CMS CE (v3.3.22 and below) contain a logic flaw allowing unauthenticated attackers to create a new administrator account. The automated control that deletes admin/setup.php after installation is neutralized by a self-exclusion bug, leaving the setup script accessible. As of publication, no patched versions are available.

The WS-Security (wsse:UsernameToken) verification routine in the Sofia IPC daemon in Xiongmai IP Camera XM530 firmware HMT.CM2005-v220608.1837 and earlier has an improper authentication vulnerability. A remote attacker can bypass authentication and execute privileged ONVIF actions (PTZ control, stream URL retrieval, system reboot) via a crafted SOAP request supplying the admin username with any arbitrary password when the account's stored password is empty.

Unauthenticated PHP Object Injection in ThemeREX Addons versions below 2.45.0.

Unauthenticated PHP Object Injection in Everest Forms versions 3.6.0 and below.

In Authorizer prior to version 2.2.1, the /authorize endpoint accepts any redirect_uri without validating it against AllowedOrigins. With response_type=token or response_type=id_token, the server appends access_token, id_token, and refresh_token as query parameters and issues a 302 redirect to the attacker-supplied URL. An unauthenticated attacker can obtain the client_id from the public /graphql endpoint.

The built-in name-finder patterns EMAIL and URL in Apache OpenNLP contain ambiguous nested quantifiers, enabling a ReDoS attack. A crafted input can trigger super-linear backtracking or unbounded matcher recursion, leading to CPU exhaustion or StackOverflowError. The issue affects versions 2.0.0 through 2.5.11 and 3.0.0-M1 through 3.0.0-M5.

SPIP before 4.4.18 contains a remote code execution vulnerability in the editer_objet action where the arg parameter resolves SQL table names without enforcing an editable columns allowlist. Attackers with a valid nonce can inject attacker-controlled rows into the spip_jobs table, and by supplying arg=job/0 with crafted fonction and args values, these are later unserialized and executed when the cron job queue is drained.

SPIP before 4.4.18 contains a missing authorization vulnerability in the administrative action endpoints under ecrire/action/ that allows unauthenticated attackers to perform privileged actions by supplying a valid HMAC-SHA256 nonce without any server-side permission check via autoriser(). Attackers can obtain a valid nonce, compute it for any action as the anonymous user, and invoke the editer_auteur action directly over HTTP to reset the password of any user account, including the administrator.

Laci Synchroni is a decentralized mod and appearance sync server and plugin for Dalamud. Versions of the backend prior to 1.2.3 have an improper authentication vulnerability in the OAuth2 login flow, relying on client-side state by trusting the UID field inside the Authentications object of a user's local config.json file. By manually editing this file before logging in, a user can supply an arbitrary UID, and because the server fails to validate that the authenticated OAuth2 identity matches the requested UID, an attacker can fully impersonate any target user and perform actions on their behalf.

CWE-303: Incorrect Implementation of Authentication Algorithm vulnerability exists that could cause loss of confidentiality, integrity and availability of the PLC provided an application project with a lower application level is running on the PLC.
