CVE-2024-13824
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 CiyaShop - Multipurpose WooCommerce Theme theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.19.0 via deserialization of untrusted input in the 'add_ciyashop_wishlist' and 'ciyashop_get_compare' functions. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
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 CiyaShop WordPress theme up to version 4.19.0 is vulnerable to PHP Object Injection via unsafe deserialization of untrusted input in the add_ciyashop_wishlist and ciyashop_get_compare functions. Unauthenticated attackers can inject arbitrary PHP objects; while no POP chain exists in the theme itself, the presence of other plugins or themes with POP chains could enable remote code execution, file deletion, or data exfiltration.

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 CiyaShop theme is installedNavigate to Appearance > Themes in WordPress admin or inspect the /wp-content/themes/ directory for a ciyashop folderAffected if The CiyaShop theme folder exists in the WordPress themes directory
-
Check installed theme versionOpen the theme's style.css file (typically in /wp-content/themes/ciyashop/) and locate the Version: header in the file comments, or check via WordPress admin theme detailsAffected if The version number displayed is less than 4.19.1 (e.g., 4.19.0 or earlier)
-
Verify vulnerable AJAX endpoints existSearch the theme's functions.php or AJAX handler files for 'add_ciyashop_wishlist' and 'ciyashop_get_compare' action hooks; these are typically registered with add_action('wp_ajax_add_ciyashop_wishlist', ...) and similarAffected if These function hooks are present and registered without nonce validation or capability checks
-
Confirm unauthenticated access is possibleExamine the AJAX hook registration to determine if wp_ajax_nopriv_ hooks are also registered (allowing unauthenticated users), e.g., add_action('wp_ajax_nopriv_add_ciyashop_wishlist', ...)Affected if The hooks include wp_ajax_nopriv_ actions, meaning unauthenticated users can trigger the vulnerable deserialization code
-
Audit for potential POP chain gadgetsReview installed plugins and themes for known POP chain classes (such as __wakeup, __destruct, or __toString methods that can be chained for RCE); check plugin/theme files in /wp-content/plugins/ and /wp-content/themes/ for unserialize() calls on user-controlled inputAffected if Additional plugins or themes with unserialize() calls and exploitable magic methods are present alongside the vulnerable theme
A user is affected if they have CiyaShop theme version below 4.19.1 installed with the vulnerable AJAX functions exposed to unauthenticated users and optionally combined with other plugins containing POP chain capabilities.

dbcve · scoped4.19.1
Update the CiyaShop theme to the latest patched version immediately and audit installed plugins/themes for the presence of POP chain capabilities that could be chained with this vulnerability.
Ciyashop theme version 4.19.1
- Log in to the WordPress admin dashboard
- Navigate to Appearance > Themes
- Locate the Ciyashop theme
- If a newer version is available, click 'Update Now' to upgrade to version 4.19.1
- Alternatively, download version 4.19.1 from the ThemeForest marketplace and upload via Appearance > Themes > Add New > Upload Theme
- After upgrading, verify the theme is running version 4.19.1 or higher under Appearance > Themes
- Test critical functionality (wishlist, compare features) to ensure the upgrade did not break site operations
