Technical Analysis
CVE-2026-113660 is a missing authorization vulnerability (CWE-862) in ApostropheCMS, an open-source Node.js content management system. The exist-in-locale API endpoint prior to version 4.33.0 improperly returns localized document identifiers to authenticated low-privilege users without enforcing document-level view or edit permissions. This allows such users to confirm the presence of restricted documents in various locales and modes, including drafts. The vulnerability is fixed in ApostropheCMS version 4.33.0.
Potential Impact
An authenticated user with low privileges can determine the existence of restricted documents in specific locales and modes, potentially exposing information about document presence that should be confidential. There is no indication of data modification or denial of service impact. The CVSS score is 4.3 (medium severity), reflecting limited confidentiality impact and no integrity or availability impact.
Mitigation Recommendations
Upgrade ApostropheCMS to version 4.33.0 or later, where this missing authorization issue is fixed. No other mitigations are specified or required.
