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 · unedited
Deserialization of Untrusted Data vulnerability in NooTheme Organici Library noo-organici-library allows Object Injection.This issue affects Organici Library: from n/a through <= 2.1.2.

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 confidence

A deserialization of untrusted data vulnerability in the NooTheme Organici Library (noo-organici-library) allows attackers to inject PHP objects via insecure deserialization, potentially leading to remote code execution or other attacks. This affects all versions up to and including 2.1.2.

MitigationUpdate the Organici Library to a patched version if available, or review and sanitize all deserialization operations in the library code to ensure only trusted data is processed. If the library is no longer maintained, consider replacing it with a secure alternative.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Locate the noo-organici-library in your codebase
    Search your project for files or directories named 'organici', 'noo-organici-library', or containing 'nootheme' in combination with 'organici'. Check your dependency management files (composer.json, package.json, or similar) for 'noo-organici-library' or 'nootheme/organici-library' as a dependency.
    Affected if The library is present in your project dependencies or file structure.
  2. Identify the installed version of the Organici Library
    Check your lock files (composer.lock, package-lock.json) or the library's main PHP file for a version declaration. If the library is included as a submodule or direct upload, inspect the main library file for a version constant or readme file.
    Affected if The version is 2.1.2 or lower, or if no version can be determined but the library is present.
  3. Inspect deserialization operations in the library code
    Search the library directory for PHP unserialize() function calls. Review any code that processes serialized data, particularly data originating from user input, HTTP requests, or external sources.
    Affected if The library contains unserialize() calls that handle data from untrusted sources without prior sanitization.
  4. Determine if the library is actively processing external data
    Review your application code that integrates the Organici Library to see if any functions that handle serialized data are being invoked during normal operation or through user-controlled inputs.
    Affected if The vulnerable deserialization functions are reachable and process data that could be controlled by an attacker.

You are affected if the noo-organici-library (version 2.1.2 or lower) is present in your environment AND its deserialization functions are processing untrusted data without validation.

Mitigation

Update the Organici Library to a patched version if available, or review and sanitize all deserialization operations in the library code to ensure only trusted data is processed. If the library is no longer maintained, consider replacing it with a secure alternative.
