Worked on the microsoft/BCApps repository to address a security issue in the email attachments feature within the Purchase Header workflow. Focused on backend development using AL and Business Central, the developer delivered a targeted bug fix that removed an overly broad ReadPermission check in the Email Impl codeunit. Instead, the solution leveraged the GetBySystemId method to ensure that row-level security filters are respected when retrieving attachments. This approach improved data privacy and compliance by enabling access only when appropriate security filters are applied to source tables, while minimizing the risk of regressions and maintaining usability for end users.
