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 rascals Noisa noisa allows Object Injection.This issue affects Noisa: from n/a through <= 2.6.0.

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

The vulnerability is a deserialization of untrusted data flaw in the Noisa application that allows remote attackers to inject arbitrary PHP objects by supplying crafted serialized data. This object injection can lead to code execution, file operations, or other malicious actions depending on available magic methods in the application environment.

MitigationUpgrade to a patched version if available, otherwise refactor code to use safe serialization formats like JSON instead of PHP unserialize() and implement strict input validation with allowlist validation for any deserialized content.

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 Noisa application installation
    Search the system for directories or files associated with the Noisa application, such as web root directories containing 'noisa' in the path, or check for installed packages related to Noisa.
    Affected if The Noisa application is found installed or deployed on the system.
  2. Identify PHP deserialization functions in the codebase
    Search the Noisa source code files (particularly PHP files) for calls to unserialize(), and review any custom deserialization logic that handles serialized data.
    Affected if The codebase contains unserialize() calls or similar PHP deserialization functions that process input data.
  3. Determine if user input reaches deserialization
    Trace the data flow from HTTP request parameters, POST data, cookies, or API inputs to identify whether any untrusted data is passed to unserialize() or deserialization functions.
    Affected if Untrusted or user-supplied data is directly or indirectly fed into deserialization functions without validation.
  4. Check for magic method definitions
    Search the Noisa codebase for PHP magic method definitions such as __wakeup(), __destruct(), __toString(), __invoke(), __get(), or __set() that could be triggered during object injection.
    Affected if The application defines magic methods that could be leveraged during object injection to execute arbitrary code or file operations.
  5. Inspect input handling configuration
    Review application configuration files, routing logic, and endpoint definitions to determine if the application accepts and processes serialized data from external sources.
    Affected if The application is configured to accept serialized data from untrusted network sources.

A user is affected if the Noisa application is installed and its codebase contains unserialize() calls that process untrusted input without proper validation.
