Local file overwrite via non-inline terminal payloads
Published Jun 24, 2026 · Updated Jun 24, 2026
Improper file handling in Warp allows remote attackers to overwrite local files by displaying crafted terminal output. The terminal model accepts attacker-controlled non-inline OSC 1337 File or multipart sequences, decodes their data, and writes the named file under the active working directory without confirmation. Exploitation requires a user to display the output; created or truncated user-writable files can enable persistence or delayed execution only if a shell, desktop environment, project tool, or Warp configuration later interprets them.
