Deeper analysis

CVE-2026-32539 is an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability that enables Blind SQL Injection in the PublishPress Revisions (revisionary) WordPress plugin. This issue affects all versions from n/a through 3.7.23.

The vulnerability has a CVSS 3.1 base score of 9.3 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L), indicating that unauthenticated attackers with network access can exploit it remotely with low complexity and no user interaction. Exploitation allows high-impact confidentiality violations, such as data exfiltration through blind SQL techniques, alongside low availability impact and a changed scope.

Patchstack's advisory (https://patchstack.com/database/Wordpress/Plugin/revisionary/vulnerability/wordpress-publishpress-revisions-plugin-3-7-23-sql-injection-vulnerability?_s_id=cve) documents the SQL injection vulnerability specifically in PublishPress Revisions plugin version 3.7.23 and provides details on affected installations for mitigation guidance.
