CVE-2026-56652: CWE-1236 Improper Neutralization of Formula Elements in a CSV File in scottchiefbaker dool
Description
Dool versions up to 1.3.8 have a CSV injection vulnerability due to improper sanitization of cell content starting with special formula characters (=, +, -, @). A local attacker can exploit this by creating a process with a crafted name that injects malicious formulas into exported CSV files, which execute when opened in spreadsheet applications. The issue was fixed by pull request #117.

Technical Analysis
CVE-2026-56652 describes a CSV injection vulnerability in the dool software by scottchiefbaker, affecting versions up to and including 1.3.8. The vulnerability arises because dool fails to neutralize formula elements in CSV exports, allowing an attacker with local access to inject malicious spreadsheet formulas by naming a process with a leading special character. This can lead to formula execution when the CSV file is opened in spreadsheet software. The vulnerability is identified as CWE-1236 and has a CVSS 4.6 (medium) score. The fix was implemented in pull request #117.
Potential Impact
A local attacker can inject malicious spreadsheet formulas into CSV files generated by dool, potentially causing unintended formula execution when the CSV is opened by a user. This could lead to data manipulation or other spreadsheet-based attacks. The impact is limited by the need for local access and user interaction to open the crafted CSV file.
Mitigation Recommendations
The vulnerability was addressed by pull request #117. Users should upgrade dool to a version later than 1.3.8 where this fix is included. No official patch version is explicitly stated, so verify the vendor repository or release notes for the fixed version. Until upgraded, avoid opening CSV files generated by untrusted local sources or sanitize CSV content manually.
