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 Funnnny HidePost plugin version <= 2.3.8 allows attackers to trick authenticated users into executing unintended requests that result in reflected XSS. The lack of proper CSRF token validation or SameSite cookie attributes enables the attack vector.

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.
-
Locate the HidePost plugin installationSearch for the Funnnny HidePost plugin directory in your web application's plugin folder (commonly /wp-content/plugins/ or similar path depending on your CMS)Affected if The HidePost plugin directory exists in your system
-
Identify the installed versionOpen the main plugin file (typically named hidepost.php or similar) and locate the version declaration in the file header commentAffected if The version number shown is 2.3.8 or lower
-
Verify the plugin is activeCheck your CMS plugin admin interface or configuration to confirm the HidePost plugin is currently enabledAffected if The plugin shows as active in your plugin management system
-
Inspect cookie configurationExamine your application or browser developer tools to check if cookies set by the HidePost plugin have SameSite attributes defined (look for SameSite=Strict or SameSite=Lax)Affected if Cookies related to HidePost lack SameSite attributes or have SameSite=None without Secure flag
-
Check form submissions for CSRF tokensReview the HTML source of any forms generated by the HidePost plugin (e.g., settings forms, post hide forms) to see if they include anti-CSRF token fieldsAffected if Forms generated by HidePost do not contain CSRF token fields or validation is missing
You are affected if the HidePost plugin version is 2.3.8 or lower AND the plugin is active AND the cookie SameSite protection is missing AND forms lack CSRF token validation.

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 on all state-changing requests and configure SameSite cookie attributes; alternatively, update HidePost to the latest version if a patched release is available.
