Technical description

n8n is an open source workflow automation platform. Prior to versions 2.10.1, 2.9.3, and 1.123.22, additional exploits in the expression evaluation of n8n have been identified and patched following CVE-2025-68613. An authenticated user with permission to create or modify workflows could abuse crafted expressions in workflow parameters to trigger unintended system command execution on the host running n8n. The issues have been fixed in n8n versions 2.10.1, 2.9.3, and 1.123.22. Users should upgrade to one of these versions or later to remediate all known vulnerabilities. If upgrading is not immediately possible, administrators should consider the following temporary mitigations. Limit workflow creation and editing permissions to fully trusted users only, and/or deploy n8n in a hardened environment with restricted operating system privileges and network access to reduce the impact of potential exploitation. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

———ArcadeDB before 26.7.2 (arcadedb-engine) allows trigger scripts to look up host classes in java.lang.* (via Java.type) because ScriptTriggerExecutor adds java.lang.* to the allowed packages. An authenticated user with UPDATE_SCHEMA permission can create a JavaScript trigger that invokes java.lang.Runtime.getRuntime().exec() (or ProcessBuilder), achieving OS command execution when the trigger fires.8h CVE-2026-161448.1 HIG

——0The Kali Forms — Contact Form & Drag-and-Drop Builder plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.4.20 via the _save_data function. This is due to insufficient validation of the 'thisPermalink' field value before it overwrites a trusted callable placeholder, allowing attacker-controlled strings to reach call_user_func() in _save_data(). This makes it possible for unauthenticated attackers to execute code on the server. Exploitation requires the target form to define a field with a name matching one of the reserved placeholder keys ('thisPermalink', 'entryCounter', or 'submission_link'), as check_if_placeholders_changed() only processes POST keys present in the form's field_type_map.12h CVE-2026-687709.8 CRI

——0sentence-transformers contains a security control bypass vulnerability that allows attackers to achieve arbitrary code execution by exploiting a logic flaw in the import_module_class helper within sentence_transformers/util/misc.py, where the guard condition includes an 'or os.path.exists(model_name_or_path)' clause that satisfies the trust gate whenever the supplied path exists on the local filesystem, regardless of the trust_remote_code=False argument. Attackers who can control or influence the contents of a model directory on disk can place malicious Python files such as modeling_*.py referenced via modules.json, causing the code to execute at import time when an application loads the model with SentenceTransformer(path, trust_remote_code=False), bypassing the documented security contract and achieving code execution within the loading process.1d CVE-2026-535108.1 HIG

——3The ElementsKit Elementor Addons WordPress plugin before 3.10.01 does not prevent a custom-widget definition saved by a user with administrative capabilities from being written verbatim into a generated PHP file that the ElementsKit Elementor Addons WordPress plugin before 3.10.01 subsequently executes, allowing arbitrary PHP code to run on the server; on a multisite network this lets a non-super subsite Administrator, who is otherwise denied code/file editing, reach host-level code execution beyond the privileges the network grants them.1d
