Unauthenticated information disclosure via REST authorization failure
Published Mar 18, 2026 · Updated Mar 18, 2026
Missing authorization in Contextual Related Posts before 4.2.2 allows remote attackers to read information through the plugin's REST API. Upstream material identifies deficient REST API permission checks and argument sanitization, but does not disclose the affected route or failed authorization decision. No authentication is required; published scoring limits the impact to information disclosure, with no data modification or service interruption reported.
