CVE-2026-27098
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 axiomthemes Au Pair Agency - Babysitting & Nanny Theme au-pair-agency allows Object Injection.This issue affects Au Pair Agency - Babysitting & Nanny Theme: from n/a through <= 1.2.2.
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 confidenceThis is a PHP Object Injection vulnerability in the Au Pair Agency WordPress theme. The theme deserializes untrusted data (likely via PHP's unserialize() function on user-controlled input), allowing attackers to inject malicious PHP objects. Depending on available 'gadgets' in the theme or other installed plugins, this can lead to remote code execution, file operations, or other attacks.

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 the Au Pair Agency theme is installedCheck your WordPress installation's wp-content/themes/ directory for a folder named 'au-pair-agency' or similar. You can also list installed themes via WordPress admin under Appearance > Themes.Affected if The theme folder exists in your themes directory.
-
Identify the installed theme versionOpen the theme's style.css file located in the theme folder and look for the 'Version:' comment header at the top. Alternatively, check theme.json for a version field.Affected if You cannot determine the version, or the version is older than the latest available (compare against the vendor's current version).
-
Locate PHP files that use unserialize()Search all PHP files within the theme folder for the pattern 'unserialize(' - use grep, a file search tool, or manually review PHP files in the theme directory.Affected if Any unserialize() call is found that processes input from $_GET, $_POST, $_REQUEST, or other user-supplied sources.
-
Verify if user-controlled data reaches unserialize()For each unserialize() call found, trace the data source. Check if the input originates from request parameters (GET/POST), cookies, or external API calls without sanitization.Affected if User-controlled input is passed directly to unserialize() without prior validation or integrity checks.
-
Review theme for available gadget chainsExamine all classes and files in the theme for magic methods (__wakeup, __destruct, __call, __toString) that could be chained for code execution if a PHP object can be injected.Affected if The theme contains classes with exploitable magic methods that could be triggered via injected objects.
You are affected if the Au Pair Agency theme is installed and contains unserialize() calls that process untrusted user input, allowing PHP object injection.

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 to the latest version of the Au Pair Agency theme if a patch is available. If no update exists, disable the theme immediately, audit the codebase for unsafe unserialize() calls on user input, and implement proper input validation or use json_decode() instead.
