CVE-2026-32539
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in PublishPress PublishPress Revisions revisionary allows Blind SQL Injection.This issue affects PublishPress Revisions: from n/a through <= 3.7.23.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA blind SQL injection vulnerability exists in the PublishPress Revisions WordPress plugin (versions up to 3.7.23). The vulnerability allows unauthenticated attackers to inject malicious SQL queries through unsanitized user input that gets directly incorporated into SQL statements, potentially enabling data exfiltration or database compromise.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check the installed version of PublishPress RevisionsNavigate to WordPress Admin > Plugins > Installed Plugins, locate 'PublishPress Revisions', and note the version number displayedAffected if The installed version is 3.7.23 or earlier (any version up to and including 3.7.23)
-
Verify the plugin is activeIn the WordPress Plugins list, confirm that PublishPress Revisions shows as 'Active'Affected if The plugin is active and the version is 3.7.23 or earlier
-
Identify the vulnerable code locationInspect the plugin files for SQL queries that incorporate user input directly, typically in files handling revision submissions or requests; look for patterns like $wpdb->prepare with unsanitized $_GET, $_POST, or $_REQUEST variablesAffected if The plugin contains code that passes user-supplied input directly into SQL statements without using $wpdb->prepare or equivalent sanitization
-
Check for suspicious database activityReview WordPress debug logs (wp-content/debug.log if enabled) and server access logs for unusual SQL syntax, long-running queries, or patterns containing UNION, SELECT, or SLEEP() in request parametersAffected if Logs contain SQL-like patterns in request parameters that suggest injection attempts or successful exploitation
-
Audit WordPress database for unauthorized changesUse a database tool (like phpMyAdmin or mysql CLI) to compare current user accounts, posts, and options against known-good backups or check for unexpected administrative users or modified capability recordsAffected if Unexpected users, especially with administrator roles, or modifications to the wp_options table that were not authorized
A user is affected if the installed PublishPress Revisions plugin version is 3.7.23 or earlier and the plugin is active, as this version contains the blind SQL injection vulnerability in unsanitized user input handling.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade PublishPress Revisions to the latest version (3.7.24 or later) which contains the patched code. If patching is immediately infeasible, consider disabling the plugin or implementing a WAF rule to block SQL injection patterns until the update can be applied.
