CVE-2025-69370
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 ThemeGoods Capella capella allows Object Injection.This issue affects Capella: from n/a through <= 2.5.5.
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 PHP Object Injection vulnerability exists in the ThemeGoods Capella theme, allowing attackers to inject malicious serialized PHP objects through untrusted input. This deserialization flaw can be leveraged to achieve remote code execution by chaining available 'gadget' classes in the application 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 Capella theme installationIdentify if the ThemeGoods Capella theme is installed in your CMS/framework. Check theme directory listings or admin panel for active themes.Affected if The Capella theme by ThemeGoods is installed or active in the environment
-
Locate deserialization functionsSearch the Capella theme files for PHP deserialization functions such as unserialize(), json_decode() with object injection potential, or similar unserialize()-like patterns.Affected if The theme contains code that deserializes untrusted data
-
Trace input to deserialization sinksAudit the identified deserialization calls to determine if user-supplied input (GET/POST parameters, cookies, headers, or database values) can reach these functions without proper validation.Affected if Untrusted user input can reach a deserialization function within the theme
-
Identify gadget class availabilityExamine the application environment for PHP classes that could be exploited as gadget chains (common ones include __wakeup(), __destruct(), __toString() methods in installed libraries or custom code).Affected if Potential gadget classes exist that could be chained for RCE
-
Check theme versionLocate the Capella theme version identifier (typically in style.css, theme.json, or a version constant) and compare against any known affected version ranges.Affected if The installed version falls within an affected range or cannot be determined
The environment is affected if the ThemeGoods Capella theme is present with deserialization sinks that accept untrusted input, allowing PHP object injection and potential RCE via gadget chaining.

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 dataUpgrade to a patched version of Capella if available; otherwise, disable or remove the theme and search for and remediate any deserialization sinks in custom code.
