Detailsinfo

A vulnerability has been found in webvitaly Page-list Plugin up to 6.2 on WordPress and classified as problematic. Affected by this vulnerability is the function pagelist_unqprfx_ext_shortcode. The manipulation of the argument show_meta_key with an unknown input leads to a authorization vulnerability. The CWE definition for the vulnerability is CWE-862. The product does not perform an authorization check when an actor attempts to access a resource or perform an action. As an impact it is known to affect confidentiality. The summary by CVE is:

The Page-list plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 6.2. This is due to the pagelist_unqprfx_ext_shortcode() function (the [pagelist_ext] / [pagelistext] shortcode) accepting attacker-controlled post_status, post_type, and show_meta_key attributes and passing them directly into get_pages() and get_post_meta() with no capability check verifying that the rendering user is permitted to read the matched objects. When the current post has no child pages, the shortcode re-issues the query with child_of => 0, broadening it to every page on the site matching the supplied status/type. This makes it possible for authenticated attackers, with contributor-level access and above, to disclose the titles, body content/excerpts, and arbitrary post meta of unrelated private and draft pages by inserting the shortcode into a contributor-authored draft and previewing it.
