On January 16-17, 2022, the CryptoBurgers play-to-earn game was exploited when the BURG token's burn function lacked access control, allowing attackers to burn tokens from the PancakeSwap liquidity pool to manipulate prices. Using flashloans, two attackers drained approximately $700K-$770K in BNB from the protocol by exploiting the unprotected burn mechanism.

There is a vulnerability in the Crypto Burger project, an NFT project on the BSC chain. "The attacker discovered a vulnerability related to the $BURG token contract, which managed to burn most of the tokens in the liquidity pool, while immediately liquidating the tokens it had previously acquired, from liquidity," the project said in a statement. $770,000 was stolen from the pool.”
