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

## 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`
- Patched in planned next release: `2026.2.24`

## Fix Commit(s)

- `9514201fb9b51de5d0b23151110d0ff5d9c8bd67`

## 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.

## Release Process Note

`patched_versions` is pre-set to the planned next release (`2026.2.24`). After npm publish, the advisory can be published without further version-field edits.
