CVE-2026-56652

Summary

Dool in versions up to 1.3.8 is vulnerable to a CSV injection vulnerability when exporting data to a CSV file, as it fails to sanitize cell content beginning with special formula characters like =, +, -, or @. A local attacker can exploit this by running a process with a crafted name starting with =, which injects malicious formulas into the CSV output that execute when a victim opens the file in a spreadsheet application.  The issue was addressed by pull request #117
