CVE-2025-27300
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 giuliopanda ADFO admin-form allows Object Injection.This issue affects ADFO: from n/a through <= 1.9.1.
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 confidenceDeserialization of Untrusted Data vulnerability in giuliopanda ADFO admin-form allows Object Injection. The admin-form component deserializes untrusted input without proper validation, enabling an attacker to inject malicious PHP objects that could lead to remote code execution.

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 ADFO admin-form componentSearch for files named 'admin-form.php' or directories containing 'adfo' or 'admin-form' within the giuliopanda installation folder, typically found in the plugins or modules directory of the CMS using this component.Affected if The giuliopanda ADFO admin-form component is present in the environment
-
Identify the installed ADFO versionOpen the main component file (usually named admin-form.php or indicated in a version.php/file) and locate the declared version number in the file header or version constant. Compare this against the fixed version 1.9.2.Affected if The installed version is earlier than 1.9.2 or the version cannot be determined (indicating an older release)
-
Determine if admin-form functionality is actively usedInspect the database for tables storing admin-form configurations or search the codebase for instances where the admin-form class is instantiated (look for 'new ADFO' or similar class instantiation patterns).Affected if Admin-form forms are created or configured in the system, meaning user input can be submitted through this component
-
Check for unsafe PHP deserialization in input handlingExamine the admin-form PHP files for usage of unserialize() function on user-submitted data (typically $_POST, $_GET, or $_REQUEST superglobals). Look for code that processes form submissions without JSON alternative or allowed_classes restriction.Affected if The component uses unserialize() on direct user input without sanitization or class allowlisting
The environment is affected if the giuliopanda ADFO admin-form component is installed with a version before 1.9.2 and the component processes user input through unsafe PHP deserialization.

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 dataReplace unsafe PHP deserialization with safer alternatives like JSON encoding, or if serialization is required, implement strict allowlist filtering with the allowed_classes parameter; also update to version 1.9.2 or later if available.
