CVE-2026-11977: WP Post Author guest-author tokens permit author-level second-order SQL injection
WP Post Author through 3.9.1 lets an Author store a crafted guest-author token through wpma_metabox_authors_list while creating or editing a post. When an administrator later loads /wp-admin/edit.php, the stored token reaches an insufficiently prepared query and the resulting value is rendered in the Authors column. The two-stage chain can extract sensitive database information. The CNA does not disclose the save handler, query-building function or complete SQL context; despite the CVSS UI:N vector, the published narrative requires the later post-list page load.
