AWS controltower: Fix broken documentation links for Control Tower parameters

Service: controltower · 2026-08-19 · Documentation low

File: controltower/latest/controlreference/elective-preventive-controls.md

Summary

Corrected multiple URLs by removing extra slashes in links to 'Configure controls with parameters' documentation.

Security assessment

The change fixes broken hyperlinks by correcting URL syntax. While the documentation discusses security controls (like ExemptedPrincipalArns), the fix itself addresses accessibility of existing content without introducing new security guidance or patching vulnerabilities.
