A file name counts as unused when nothing exists at that path, which holds for a dangling symlink, and the body file is then opened in a way that follows the link.\n\nWhen the output base is writable by other users, as with output_under(\"/tmp\"), a local user can pre-create the directory with a symlink named like an attachment. The parser then writes the attachment to the link target with the privileges of the parsing process."}], "lastModified": "2026-10-29T15:11:53.000", "sourceIdentifier": "9b29abf9-4ab0-4765-b253-1875cd9b441e"}
