CVE-2025-31422
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 designthemes Visual Art | Gallery WordPress Theme visual-arts allows Object Injection.This issue affects Visual Art | Gallery WordPress Theme: from n/a through <= 2.4.
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 confidenceThe Visual Art | Gallery WordPress Theme (visual-arts) contains a PHP Object Injection vulnerability due to insecure deserialization of untrusted data. Attackers can craft malicious serialized PHP objects and inject them via vulnerable parameters, potentially executing arbitrary code if suitable gadget chains exist in the WordPress environment.

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 visual-arts theme is installedCheck wp-content/themes/ directory for the visual-arts folder, or look in WordPress admin under Appearance > ThemesAffected if The visual-arts theme folder exists in the WordPress installation
-
Identify the installed theme versionOpen the style.css file in wp-content/themes/visual-arts/ and look for the 'Version:' header in the file commentsAffected if The version found is lower than any patched version released by the vendor, or if no version information is available but the theme is present
-
Check for deserialization sinks in theme filesSearch theme PHP files for unserialize() calls, particularly those handling user input from $_GET, $_POST, or $_REQUEST parametersAffected if Code contains unserialize() calls processing untrusted input without prior sanitization
-
Identify vulnerable parameter entry pointsReview theme PHP files for $_GET, $_POST, or $_REQUEST usage passed to deserialization functionsAffected if Parameters accepting serialized data are accessible without authentication or validation
-
Look for signs of exploitationReview wp-content/uploads/, theme directories, and recently modified PHP files for suspicious code; check access logs for unusual serialized data patternsAffected if Unexpected PHP files exist, or logs show requests containing serialized PHP object strings (O:%%3A, a:%%3A, etc.)
-
Verify gadget chain availabilityList installed plugins that may provide PHP object injection gadget chains (common targets: popular plugins with __wakeup or __destruct methods)Affected if Vulnerable theme is active AND plugins with exploitable gadget chains are installed alongside it
If the visual-arts theme is installed and processes untrusted serialized data via accessible parameters, the environment is likely affected; exploitation also requires gadget chains from plugins or other components.

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 theme to a patched version if available; otherwise remove or replace the theme. Conduct a security audit to check for signs of exploitation.
