Affected packages
• npm openclaw: < 2026.2.14 → fixed in 2026.2.14
• npm clawdbot: <= 2026.1.24-3 (no fix yet)
Description
Summary
Telegram allowlist authorization could match on `@username` (mutable/recyclable) instead of immutable numeric sender IDs.
Impact
Operators who treat Telegram allowlists as strict identity controls could unintentionally grant access if a username changes hands (identity rebinding/spoof risk). This can allow an unauthorized sender to interact with the bot in allowlist mode.
Affected Packages / Versions
• npm `openclaw`: <= 2026.2.13
• npm `clawdbot`: <= 2026.1.24-3
Fix
Telegram allowlist authorization now requires numeric Telegram sender IDs only. `@username` allowlist principals are rejected.
A security audit warning was added to flag legacy configs that still contain non-numeric Telegram allowlist entries.
`openclaw doctor --fix` now attempts to resolve `@username` allowFrom entries to numeric IDs (best-effort; requires a Telegram bot token).
