OpenClaw: Unauthorized Telegram Senders Trigger Media Download and Disk Write Before Access Check

  • Disclosed: 03.03.2026
  • Updated: 11.10.2026 10:22

Impact

In Telegram DM mode, inbound media was downloaded and written to disk before sender authorization checks completed. An unauthorized sender could trigger inbound media download/write activity (including media groups) even when DM access should be denied.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published version currently affected: 2026.2.23
  • Vulnerable range: <= 2026.2.23

Technical Details

The Telegram handler flow now enforces DM authorization before media download/write paths execute, including media-group handling. Inbound channel activity tracking was also moved to run after DM authorization in the Telegram message context path.
