Does this affect you?

It affects OpenClaw. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

OpenClaw (npm package `openclaw`) before 2026.8.1 does not neutralize leading characters that spreadsheet applications interpret as formulas when the Control UI exports session data to CSV. Although session labels were quoted as CSV text, a lower-trust participant who can influence a session label or the first user message can place a formula-like cell in the Usage export; if an operator opens that export in a spreadsheet application with formula evaluation enabled, the cell may be evaluated with the permissions of the spreadsheet user. OpenClaw itself does not evaluate the formula, and practical impact depends on the spreadsheet application's security settings. The issue is fixed in 2026.8.1.
