CVE-2019-25340Public exploit

Application crash via oversized Base64 field input

Published Feb 12, 2026 · Updated Feb 12, 2026

Stack-based buffer overflow in Nsasoft SpotAuditor 5.3.2 allows local users to crash the application through oversized Base64 input. The Base64 decryption dialog accepts a 2,000-character value in the Base64 Encrypted Password field without enforcing its stack-buffer limit. Triggering the crash requires local GUI access to paste the value and select Decrypt; no broader impact is demonstrated.
