Flowise · Flowise · CVE-2026-73484
**Name of the Vulnerable Software and Affected Versions**
Flowise versions prior to 3.1.3
**Description**
A sandbox escape exists in `pythonCodeValidator.ts` because it fails to block native Pandas DataFrame methods, including `to csv`, `to json`, `pipe`, and `query`. Authenticated attackers can leverage this to exfiltrate uploaded CSV data or write arbitrary files to the server filesystem.
**Recommendations**
Update to version 3.1.3 or later.
