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).
