Lifecycle Timeline
3DescriptionGitHub Advisory
OpenClaw is a personal AI assistant. Prior to version 2026.2.15, in some shared-agent deployments, OpenClaw session tools (sessions_list, sessions_history, sessions_send) allowed broader session targeting than some operators intended. This is primarily a configuration/visibility-scoping issue in multi-user environments where peers are not equally trusted. In Telegram webhook mode, monitor startup also did not fall back to per-account webhookSecret when only the account-level secret was configured. In shared-agent, multi-user, less-trusted environments: session-tool access could expose transcript content across peer sessions. In single-agent or trusted environments, practical impact is limited. In Telegram webhook mode, account-level secret wiring could be missed unless an explicit monitor webhook secret override was provided. Version 2026.2.15 fixes the issue.
AnalysisAI
OpenClaw AI assistant versions prior to 2026.2.15 allow local authenticated users to access session transcripts across peer accounts in multi-user shared-agent deployments due to insufficient session targeting restrictions. Additionally, Telegram webhook mode may fail to properly validate per-account secrets, potentially allowing unauthorized webhook access. The vulnerability primarily impacts multi-user environments with untrusted peers, while single-user or trusted deployments face limited practical risk.
