How to Fix CVE-2026-44262

To remediate this vulnerability, upgrade all affected Dedoc/scramble dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

dedoc/scramble fixed: 0.13.22 
Upgrade dedoc/scramble to 0.13.22
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for dedoc/scramble

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-44262, inspect your project dependencies for Dedoc/scramble:

inspect dependencies for dedoc/scramble

Analyze the terminal output to locate any version of Dedoc/scramble in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.13.22), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Dedoc/scramble, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact A remote code execution (RCE) vulnerability affects versions `0.13.2` through `0.13.21`. When documentation endpoints are publicly accessible and validation rules reference user-controlled input, request supplied data may be evaluated during documentation generation, leading to execution of arbitrary PHP code in the application context. ### Patches Fixed in version `0.13.22`. ### Workarounds If upgrading is not immediately possible: * Restrict access to documentation endpoints (`/docs/api`, `/docs/api.json`) * Avoid using user-controlled variables inside validation rule expressions (e.g., values derived from request input) * Disable documentation endpoints in production environments if not required These measures significantly reduce or prevent exploitability.
