CVE-2026-22483
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 · uneditedCross-Site Request Forgery (CSRF) vulnerability in winkm89 teachPress teachpress allows Cross Site Request Forgery.This issue affects teachPress: from n/a through <= 9.0.12.
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 · moderate confidenceCross-Site Request Forgery (CSRF) vulnerability in teachPress plugin versions up to 9.0.12 allows attackers to trick authenticated users into performing unintended actions by forging HTTP requests, as the application lacks proper anti-CSRF token validation on state-changing operations.

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.
-
Verify teachPress plugin is installedNavigate to WordPress admin > Plugins and confirm teachPress appears in the list of installed plugins, or inspect the file system at /wp-content/plugins/teachpress/ for the existence of the plugin directoryAffected if teachPress plugin is present in the WordPress installation
-
Determine installed teachPress versionCheck the plugin header in teachpress.php file for the Version field, or view the version displayed in the WordPress Plugins admin pageAffected if the reported version is 9.0.12 or any earlier version (versions prior to the fix)
-
Inspect plugin forms for nonce fieldsView page source of teachPress admin pages (e.g., course management, participant list) and search for wpnonce, _wpnonce, or nonce_field in <input> tags within formsAffected if forms lack any nonce input field or the hidden nonce token is missing
-
Check AJAX handlers for nonce verificationExamine teachPress PHP files in /ajax/ folder (or similar) and look for calls to check_ajax_referer() or wp_verify_nonce() before processing state-changing requestsAffected if AJAX endpoints do not call nonce verification functions prior to executing actions
-
Verify SameSite cookie configurationInspect HTTP response headers when logging into WordPress admin and check if session cookies have SameSite attribute set (can view via browser DevTools > Network tab)Affected if session cookies lack SameSite attribute or have it set to None without Secure flag
A user is affected if teachPress version 9.0.12 or earlier is installed AND any state-changing forms or AJAX endpoints lack proper nonce verification.

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 dataImplement anti-CSRF tokens (nonces) on all forms and AJAX endpoints that perform state-changing operations, validate these tokens server-side, and configure SameSite attributes on session cookies.
