Scramble vulnerable to remote code execution via evaluation of user-controlled input in validation rules
GitHub lists this reviewed advisory for dedoc/scramble. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning

02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
dedoc/scramble
source listed>= 0.13.2, <= 0.13.21
### 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.

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. FIRST EPSS
- vendor patch
The original advisory lists fixed boundaries 0.13.22 for dedoc/scramble. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
