CVE-2025-71242
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSPIP before 4.3.6, 4.2.17, and 4.1.20 allows unauthorized content disclosure in the private area. The application does not properly check authorization when displaying content of articles and sections (rubriques) in AJAX-loaded fragments, allowing an authenticated attacker to access restricted content. This vulnerability is not mitigated by the SPIP security screen.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSPIP CMS before 4.3.6, 4.2.17, and 4.1.20 contains an authorization bypass vulnerability in AJAX-loaded fragments. The application fails to properly enforce authorization checks when rendering articles and sections (rubriques) in the private area, allowing authenticated attackers to access restricted content that should be hidden from their permission level.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify SPIP versionCheck the version.php file in the root directory, or access the administration area and look for the version number displayed in the footer or in the maintenance sectionAffected if The installed version is >= 4.1.0 and < 4.1.20, OR >= 4.2.0 and < 4.2.17, OR >= 4.3.0 and < 4.3.6
-
Confirm private area is accessibleAttempt to access the private area (/ecrire/ or /?exec=accueil) with a low-privilege user account that has restricted permissions to certain articles or sectionsAffected if The private area loads and displays content for articles or sections (rubriques) that the user account should not have permission to view
-
Test AJAX-loaded fragment behaviorUse browser developer tools to observe AJAX requests when navigating the private area, or inspect the HTML source of pages in the private area to identify AJAX-loaded fragments containing article or section contentAffected if AJAX requests load fragments containing articles or rubriques that should be hidden based on the user's permission level but are displayed anyway
-
Verify authorization enforcement on restricted contentCreate or use an existing user account with limited permissions (e.g., a visitor or editor with no access to certain sections), then attempt to access pages in the private area that contain restricted articles or rubriques via AJAX-loaded fragmentsAffected if The restricted content is visible or accessible to the user despite lacking proper authorization for that content
You are affected if your SPIP installation version is within the ranges 4.1.0-4.1.19, 4.2.0-4.2.16, or 4.3.0-4.3.5 AND the private area is accessible to users who can trigger AJAX-loaded fragments to bypass authorization checks on restricted articles or sections.

dbcve · scoped4.1.204.2.174.3.6
Upgrade SPIP to version 4.3.6, 4.2.17, or 4.1.20 or later to resolve the improper authorization checks in AJAX-loaded fragments.
Upgrade to SPIP 4.3.6 (latest stable release) or at minimum to your branch's fixed version: 4.1.20, 4.2.17, or 4.3.6
- 1. Create a complete backup of your SPIP database and all site files before proceeding
- 2. Download the appropriate fixed version from the official SPIP repository (spip.net) - choose 4.3.6 (latest stable), 4.2.17, or 4.1.20 based on your current branch
- 3. Place your site in maintenance mode or inform users of expected downtime
- 4. Upload and extract the new SPIP core files, replacing the existing /ecrire/ and other core directories
- 5. Ensure configuration files (config/mes_options.php) are preserved during the upgrade
- 6. Run the database upgrade script by accessing your site through the web browser - SPIP will automatically detect and apply necessary schema updates
- 7. Clear any caching systems (file cache, opcache, CDN) to ensure new code is loaded
- 8. Verify the upgrade by logging in and checking that articles/sections display correctly with proper authorization enforcement
