To remediate Access Control Violation issues when suggested fixes can't be implemented due to managed package constraints, consider these approaches:
1. **Evaluate Alternative Configurations**: For example, if the issue involves settings like `isExposed`, create new components or configurations that align with security guidelines, such as setting `isExposed` to `false` and using secure alternatives like the `pubsub` module for communication.
2. **Document Constraints and Submit for Review**: Clearly document the constraints preventing the implementation of suggested fixes. Include detailed use cases, supporting code snippets, and any validation mechanisms you plan to implement. Submit this documentation as part of a support case for review.
3. **Request Provisional Approval**: If the constraints are unavoidable, request a provisional pass for the specific issue while ensuring all other vulnerabilities are addressed.
4. **Consult with the Security Team**: Schedule a technical office hours appointment or open a support case to discuss the constraints and explore potential solutions with the Product Security team.
These steps can help address the issue while working within managed package limitations.
