OpenClaw npm package versions before 2026.8.1 do not properly neutralize leading characters in session data exports to CSV that spreadsheet applications interpret as formulas. This can allow a lower-trust participant who controls session labels or the first user message to inject formula-like cells into CSV exports. When opened in spreadsheet software with formula evaluation enabled, these cells may be executed with the permissions of the spreadsheet user. The vulnerability does not involve OpenClaw itself executing formulas, and the impact depends on the spreadsheet application's security settings. The issue is fixed in version 2026.8.1.
AI Analysis
Technical Summary
The OpenClaw npm package prior to version 2026.8.1 fails to neutralize leading characters in CSV exports that spreadsheet applications interpret as formulas. This allows an attacker with the ability to influence session labels or the first user message to inject formula-like content into exported CSV files. If an operator opens such a file in a spreadsheet application with formula evaluation enabled, the formula may be executed with the user's permissions. The vulnerability is mitigated by quoting session labels as CSV text, but this is insufficient to prevent formula injection. OpenClaw itself does not evaluate these formulas. The vulnerability is addressed in version 2026.8.1.
Potential Impact
An attacker with the ability to influence session labels or the first user message can inject formula-like content into CSV exports. If these exports are opened in spreadsheet applications with formula evaluation enabled, the formulas may be executed with the permissions of the spreadsheet user, potentially leading to information disclosure or other impacts depending on the spreadsheet application's security model. The vulnerability does not allow direct code execution within OpenClaw but relies on the spreadsheet application's behavior.
Mitigation Recommendations
A fix is available in OpenClaw version 2026.8.1. Users should upgrade to this version to ensure that leading characters in CSV exports are properly neutralized to prevent formula injection. No additional mitigation is required if the upgrade is applied.
