Alert meAnalysisAIv1 – Mar 12, 2026
OpenClaw versions prior to 2026.2.15 expose Telegram bot tokens in error messages and logs without redaction, allowing attackers who gain access to these logs to impersonate the bot and hijack its API access. This credential disclosure affects users of the AI assistant across systems where logs, crash reports, or support bundles are generated. Users must upgrade to version 2026.2.15 and rotate exposed Telegram bot tokens immediately.
