CVE-2025-68903
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 · uneditedDeserialization of Untrusted Data vulnerability in AivahThemes Anona anona allows Object Injection.This issue affects Anona: from n/a through <= 8.0.
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 confidenceA deserialization vulnerability in the AivahThemes Anona WordPress theme allows untrusted user-supplied data to be deserialized, enabling PHP Object Injection attacks. Attackers can potentially exploit this to execute arbitrary code, read sensitive files, or perform other malicious actions depending on available classes.

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 Anona theme installationSearch the web server document root for directories named 'anona', 'Anona', or files containing 'Anona theme' in theme header comments (usually in style.css or functions.php)Affected if The Anona theme is present in the environment
-
Find unserialize() calls in theme PHP filesUse grep or similar tool to search for 'unserialize(' recursively within the Anona theme directoryAffected if Any unserialize() calls exist in the theme's PHP files
-
Identify unserialize() data sourcesExamine each unserialize() call found and trace back to determine if input comes from user-controlled sources such as $_GET, $_POST, $_COOKIE, $_REQUEST, or database fieldsAffected if Unserialize processes data from untrusted user input without validation
-
Check for dangerous magic methods in the themeSearch for PHP magic methods like __destruct, __wakeup, __toString, or __invoke within the theme's class files that could be exploited for code executionAffected if The theme contains classes with magic methods that could be triggered during deserialization
-
Verify theme is actively loadedConfirm the Anona theme is enabled on a running WordPress or CMS instance by checking the active theme configurationAffected if The Anona theme is the currently active theme handling requests
If the Anona theme is installed and contains unserialize() calls processing untrusted input, the environment is likely 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.
From vendor dataUpdate the Anona theme to a patched version if available. If no patch exists, identify and remove the insecure deserialization calls (unserialize()) and replace with safer alternatives like json_decode(). Review server logs for signs of exploitation.
