Executive Summary

OpenClaw versions before 2026.8.1 fail to properly neutralize spreadsheet formula characters in participant display names during attendance CSV exports. This allows attackers to inject formula-like cells that execute with the spreadsheet user's permissions when the file is opened in formula-enabled applications.

Detection Guidance

Check exported CSV files from OpenClaw for participant display names starting with formula characters like '=' or '+'. Inspect files manually or use grep to search for such patterns in attendance exports.

Impact Analysis

If you export attendance data from OpenClaw versions before 2026.8.1, a malicious participant could inject harmful formulas into their display name. When you open the CSV in a spreadsheet program that supports formulas, these cells may execute automatically, potentially leading to unauthorized actions or data exposure depending on your spreadsheet settings.

Compliance Impact

This vulnerability could lead to unauthorized data access or manipulation, which may violate compliance requirements under GDPR (data protection) or HIPAA (health information privacy). Organizations using vulnerable versions risk non-compliance if the attack results in data breaches or unauthorized processing of sensitive information.

Mitigation Strategies

Upgrade OpenClaw to version 2026.8.1 or later. If immediate upgrade isn't possible, import attendance exports as plain text and inspect cells before opening in spreadsheet software.
