Security readout for executives and security teams
Plain-English summary
CVE-2026-27745 is a high-severity authenticated code execution flaw in the SPIP interface_traduction_objets plugin before 2.2.2. An attacker who already has editor-level access could make the web server run code. This is most urgent for SPIP sites using this plugin where many users have editorial access.
Executive priority
Prioritize remediation for internet-facing SPIP sites using this plugin, especially where multiple editors exist. Treat as high priority because successful abuse can lead to full web-server compromise, even though authentication is required and active exploitation is not documented in the provided sources.
Technical view
The issue is described as CWE-94 in the plugin’s translation interface workflow. Untrusted request data is placed into a hidden field rendered without SPIP output filtering. Underscore-prefixed fields bypass protections, allowing crafted content to reach SPIP’s template processing chain and execute as the web server. CVSS is 8.8, requiring low privileges and no user interaction.
Likely exposure
Exposure appears limited to SPIP installations with the interface_traduction_objets plugin installed at versions before 2.2.2 and attacker access to an editor-level account. Public-facing SPIP sites are more exposed if editorial accounts are weakly protected or broadly assigned.
Exploitation context
The source bundle includes a technical write-up and third-party advisory, but does not provide evidence of active exploitation. The vulnerability requires authenticated editor-level privileges, which reduces opportunistic internet-wide risk but remains serious after account compromise or insider misuse.
Researcher notes
The provided affected metadata is inconsistent, listing version "0" while the description states versions prior to 2.2.2. Base validation on installed plugin presence and version. Avoid assuming broader SPIP core impact beyond the cited advisory and plugin references.
Mitigation direction
- Upgrade interface_traduction_objets to version 2.2.2 or later if applicable.
- Review the SPIP security advisory and plugin page for current vendor guidance.
- Restrict editor-level accounts to trusted users only.
- Enforce strong authentication for SPIP editorial accounts.
- Monitor SPIP logs for unusual translation-interface activity.
Validation and detection
- Inventory SPIP sites and installed plugins.
- Confirm whether interface_traduction_objets is installed.
- Check the installed plugin version against 2.2.2.
- Verify editor-level accounts and recent access activity.
- Confirm the patch commit or updated package is deployed.

Improper Control of Generation of Code ('Code Injection')
Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
