CVE-2026-42755
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 RealMag777 TableOn posts-table-filterable allows Blind SQL Injection.This issue affects TableOn: from n/a through <= 1.0.5.1.
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 TableOn WordPress plugin (versions <= 1.0.5.1). The vulnerability allows unauthenticated attackers to inject malicious SQL queries through unsanitized user input in the posts-table-filterable component. The 'blind' classification means attackers infer database information through response differences rather than seeing direct output.

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.
-
Confirm TableOn plugin is installedLog into WordPress admin dashboard, navigate to Plugins > Installed Plugins, and look for 'TableOn' in the list of active pluginsAffected if TableOn plugin appears in the installed plugins list
-
Identify installed TableOn versionIn the WordPress plugins list, click on 'Plugin Details' for TableOn or inspect the plugin header in wp-content/plugins/tableon/tableon.php to read the 'Version' fieldAffected if The installed version is 1.0.5.1 or any lower version (e.g., 1.0.5, 1.0.4, 1.0.3, etc.)
-
Verify posts-table-filterable component is activeCheck WordPress pages or widgets where the [tableon] shortcode includes the 'filterable' attribute, or review the TableOn settings for any enabled filtering functionalityAffected if The posts-table-filterable feature is enabled or any table with filtering capability is published on the site
-
Inspect HTTP access logs for SQL injection probesReview web server access logs (Apache, Nginx, or CDN logs) for requests to WordPress endpoints containing SQL meta-characters in query parameters such as ', (, AND, OR, SLEEP, or UNION, especially targeting pages with TableOn shortcodesAffected if Suspicious SQL injection payloads are found in request logs targeting the site
You are affected if the TableOn plugin version is 1.0.5.1 or lower AND the posts-table-filterable component is active on any published page or widget.

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 TableOn to the latest version which should contain parameterized queries or input sanitization. If no patch is available, disable the plugin until a fix is released, or implement a WAF rule to block SQL injection payloads in the affected parameters.
