What
The permissions.blockReadsOutsideWorkingDirectories setting stops Claude Code from reading files outside the folders you are working in. Files passed through for upload are now checked against it too. If the setting blocks a file, Claude Code stops with the error "read not allowed under permissions.blockReadsOutsideWorkingDirectories".
Why
If you rely on this setting to keep Claude Code inside your working folders, uploads can no longer be used to get around it.
