CVE-2023-6748Network attack vector

Contributor-level metadata disclosure via unchecked shortcode post ID

Published Jun 11, 2024 · Updated Apr 8, 2026

Missing authorization in Custom Field Template 2.6.1 and earlier allows remote authenticated users to read arbitrary post metadata. The cft shortcode accepts a caller-supplied post_id and returns that post's metadata without verifying access to the selected post. Contributor-level access is sufficient, and the disclosure is limited to metadata returned through the crafted shortcode request.
