CVE-2022-4555
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 · uneditedThe WP Shamsi plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the deactivate() function hooked via init() in versions up to, and including, 4.1.0. This makes it possible for unauthenticated attackers to deactivate arbitrary plugins on the site. This can be used to deactivate security plugins that aids in exploiting other vulnerabilities.
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 confidenceThe WP Shamsi plugin for WordPress versions up to 4.1.0 has a missing capability check on the deactivate() function hooked via init(). This allows unauthenticated attackers to send requests that deactivate arbitrary plugins on the site, including security plugins, creating a pathway to exploit other vulnerabilities.

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 WP Shamsi plugin is installedCheck the wp-content/plugins directory for a folder named 'wp-shamsi' or 'shamsi-date', or use WP-CLI: wp plugin list --status=active --format=csvAffected if The plugin folder exists in wp-content/plugins/ and the plugin is active
-
Identify installed versionRead the plugin header from wp-content/plugins/wp-shamsi/wp-shamsi.php (or main plugin file) to find the 'Version:' field, or run: wp plugin get wp-shamsi --format=jsonAffected if Version is less than 4.1.1 (e.g., 4.1.0, 4.0.x, etc.)
-
Confirm vulnerable function existsInspect the main plugin PHP file for a function named deactivate() hooked via add_action('init', 'deactivate') or similar, or check for any public function handling plugin deactivation without a capability checkAffected if A deactivate function hooked to init() is present without current_user_can() or a capability check before performing the deactivation action
If WP Shamsi is installed with a version below 4.1.1 and contains an unprotected deactivate function hooked to init(), the site is affected by this vulnerability.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped4.1.1
Update the WP Shamsi plugin to version 4.1.1 or later which includes proper capability checks on the deactivate() function. Until the update is applied, consider deactivating the plugin or implementing WAF rules to block requests targeting the plugin's deactivate functionality.
WP Shamsi version 4.1.1
- 1. Create a full backup of the WordPress site (database and files) before making any changes
- 2. Navigate to the WordPress admin dashboard
- 3. Go to Plugins > Installed Plugins
- 4. Locate the 'WP Shamsi' plugin in the list
- 5. Click 'Update now' if an update is available, or manually upload version 4.1.1 from the WordPress plugin repository
- 6. Verify the plugin is running version 4.1.1 or later after updating
- 7. Test that the plugin functionality still works as expected
- 8. Verify that other plugins (especially security plugins) are still active
