Description
SPIP 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.
Product status
4.1.0 (semver) before 4.1.20
4.2.0 (semver) before 4.2.17
4.3.0 (semver) before 4.3.6
