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 · unedited
Cross-Site Request Forgery (CSRF) vulnerability in Dinesh Karki Block Plugin Update plugin <= 3.3 versions.

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 confidence

Cross-Site Request Forgery (CSRF) vulnerability in the Dinesh Karki Block Plugin Update WordPress plugin versions 3.3 and below. The plugin lacks proper CSRF protection mechanisms, allowing attackers to trick authenticated administrators into performing unintended actions such as blocking plugin updates or modifying plugin settings via maliciously crafted requests.

MitigationUpdate the Block Plugin Update plugin to the latest version which includes proper CSRF token validation and nonce verification for all state-changing operations. If no update is available, consider disabling the plugin until a patch is released.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify plugin is installed
    Navigate to WordPress admin dashboard > Plugins > Installed Plugins. Look for 'Block Plugin Update' by Dinesh Karki in the list.
    Affected if The plugin appears in the installed plugins list
  2. Check installed version number
    In the Plugins list, look under the plugin name for the version number, or click on the plugin and view the plugin details popup which displays the version.
    Affected if Version number displayed is 3.3 or lower (for example 3.3, 3.2, 3.1, etc.)
  3. Confirm plugin is active
    In Plugins > Installed Plugins, check if 'Block Plugin Update' shows 'Active' status under the plugin name.
    Affected if Plugin is active (inactive plugins would not be exploitable for CSRF)
  4. Identify vulnerable state-changing actions
    Access the plugin settings page (usually under Settings > Block Plugin Update or similar). Look for options that modify plugin behavior such as blocking updates or changing configuration.
    Affected if Plugin settings page exists and contains toggle/checkboxes for blocking plugin updates or modifying plugin settings - these are the actions that lack CSRF protection

User is affected if the Block Plugin Update plugin is installed, active, and running version 3.3 or below, with accessible settings that allow state changes.
