AWS mediatailor documentation change
Summary
Added documentation for new `scte.segmentation_upid.private_data.{index}` session variables, updated section titles, and rephrased content about session variables for ADS requests. Includes examples of parsing private UPID data from SCTE signals.
Security assessment
The new `scte.segmentation_upid.private_data` variables document how to handle private UPID data used in targeted advertising workflows. While this relates to data handling, there is no evidence of a security vulnerability being patched. The change adds documentation about a security-adjacent feature (data parsing for ads) but does not address a specific security issue.
