This is primarily a configuration/visibility-scoping issue in multi-user environments where peers are not equally trusted.\n\nIn Telegram webhook mode, monitor startup also did not fall back to per-account `webhookSecret` when only the account-level secret was configured.\n\n## Typical Use Case Context\n\nMost regular OpenClaw deployments run a single agent, or run in trusted environments. In those setups, practical risk from this issue is generally low.\n\n## Impact\n\n- Shared-agent, multi-user, less-trusted environments: session-tool access could expose transcript content across peer sessions.\n- Single-agent or trusted environments: practical impact is limited.\n- Telegram webhook mode: account-level secret wiring could be missed unless an explicit monitor webhook secret override was provided.\n\n## Affected Packages / Versions\n\n- Package: npm `openclaw`\n- Affected versions: `<= 2026.2.14`\n- Patched version: `2026.2.15` (planned next release)\n\n## Remediation\n\n- Add and enforce `tools.sessions.visibility` (`self | tree | agent | all`) across session tools, defaulting to `tree`.\n- Keep sandbox clamping behavior so sandboxed runs can be restricted to spawned/session-tree visibility.\n- Resolve Telegram webhook secret from account config fallback in monitor webhook startup.\n\n## Fix Commit(s)\n\n- `c6c53437f7da033b94a01d492e904974e7bda74c`\n\nThanks @aether-ai-agent for reporting.",

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.",

This is primarily a configuration/visibility-scoping issue in multi-user environments where peers are not equally trusted.\n\nIn Telegram webhook mode, monitor startup also did not fall back to per-account `webhookSecret` when only the account-level secret was configured.\n\n## Typical Use Case Context\n\nMost regular OpenClaw deployments run a single agent, or run in trusted environments. In those setups, practical risk from this issue is generally low.\n\n## Impact\n\n- Shared-agent, multi-user, less-trusted environments: session-tool access could expose transcript content across peer sessions.\n- Single-agent or trusted environments: practical impact is limited.\n- Telegram webhook mode: account-level secret wiring could be missed unless an explicit monitor webhook secret override was provided.\n\n## Affected Packages / Versions\n\n- Package: npm `openclaw`\n- Affected versions: `<= 2026.2.14`\n- Patched version: `2026.2.15` (planned next release)\n\n## Remediation\n\n- Add and enforce `tools.sessions.visibility` (`self | tree | agent | all`) across session tools, defaulting to `tree`.\n- Keep sandbox clamping behavior so sandboxed runs can be restricted to spawned/session-tree visibility.\n- Resolve Telegram webhook secret from account config fallback in monitor webhook startup.\n\n## Fix Commit(s)\n\n- `c6c53437f7da033b94a01d492e904974e7bda74c`\n\nThanks @aether-ai-agent for reporting.",
