# #34959 \[SC-Low] \`mintDebt\` returns a wrong value **Submitted on Sep 1st 2024 at 21:26:18 UTC by @Bx4 for** [**Audit Comp | Acre**](https://immunefi.com/audit-competition/boost-acre) * **Report ID:** #34959 * **Report Type:** Smart Contract * **Report severity:** Low * **Target:** * **Impacts:** * Contract fails to deliver promised returns, but doesn't lose value * wrong return value ## Description ## Brief/Intro In \`mintDebt\` it returns \`shares\` but it is rather supposed to return assets ## Vulnerability Details In \`mintDebt\` it returns \`shares\` as seen below \`return shares;\` meanwhile it is stated in the function natspec to return assets as seen below \`/// @return assets The debt amount in asset taken for the shares minted.\` Also, it is seen in the function declaration that it returns assets as shown below \` function mintDebt( uint256 shares, address receiver) public whenNotPaused returns (uint256 assets){} \` However the return statement declared last will overwrite it. ## Impact Details it will return a wrong value and it will break the ERC 4626 invariant because it is stated that mint functions return assets as seen in this [link](https://ethereum.org/en/developers/docs/standards/tokens/erc-4626/#mint). ## References ## Proof of Concept ## Proof of Concept from the comment(@return) and the return value of the \`mintDebt\` function below \`\`\`solidity /// @return assets The debt amount in asset taken for the shares minted. function mintDebt( uint256 shares, address receiver ) public whenNotPaused returns (uint256 assets) { ... @-> return shares; } \`\`\` we can deduce that the return value is supposed to be assets and yes in the function declaration it returns \`uint256 assets\`, However the last return statement will overwrite it and return shares --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
