How Does a High-Slippage Tolerance Make a User More Vulnerable to Sandwich Attacks?

A high slippage tolerance signals to the attacker that the user is willing to accept a wide range of execution prices. The attacker can place their front-run trade, driving the price up, and the victim's trade will still execute successfully because the new, worse price falls within the allowed tolerance.

This guarantees the attacker a profit from the back-run trade, making the user's high tolerance an explicit invitation for a sandwich attack.
