Aliases CVE-2026-28480
Summary OpenClaw Telegram allowlist authorization accepted mutable usernames ## 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). ## Fix Commit(s) - e3b432e481a96b8fd41b91273818e514074e05c3 - 9e147f00b48e63e7be6964e0e2a97f2980854128 Thanks @vincentkoc for reporting.
