Received Received - Intake
Authenticated Remote Code Execution in SPIP interface_traduction_objets Plugin

Publication date: 2026-02-25

Last updated on: 2026-02-27

Assigner: VulnCheck

Description
The SPIP interface_traduction_objets plugin versions prior to 2.2.2 contain an authenticated remote code execution vulnerability in the translation interface workflow. The plugin incorporates untrusted request data into a hidden form field that is rendered without SPIP output filtering. Because fields prefixed with an underscore bypass protection mechanisms and the hidden content is rendered with filtering disabled, an authenticated attacker with editor-level privileges can inject crafted content that is evaluated through SPIP's template processing chain, resulting in execution of code in the context of the web server.

Mitigation Strategies

To mitigate the CVE-2026-27745 vulnerability, you should update the SPIP interface_traduction_objets plugin to version 4.3.3 or later, where the issue has been fixed.

The fix involves applying proper sanitization best practices to prevent injection of untrusted data and ensuring that CSS resources are correctly sanitized and timestamped to manage caching effectively.

  • Identify if your system uses the interface_traduction_objets plugin version prior to 4.3.3.
  • Upgrade the plugin to version 4.3.3 or newer as soon as possible.
  • Restrict editor-level privileges to trusted users only, as the vulnerability requires authenticated editor-level access.
