Severity:
fund.amount_raised is not reset after withdrawal in withdraw()
Summary
fund.amount_raised is not reset after withdrawal in withdraw()
Vulnerability Details
The withdraw function transfers all funds from the fund account to the creator account but does not reset fund.amount_raised after the withdrawal.
pub fn withdraw(ctx: Context<FundWithdraw>) -> Result<()> {
let amount = ctx.accounts.fund.amount_raised;
**ctx.accounts.fund.to_account_info().try_borrow_mut_lamports()? =
ctx.accounts.fund.to_account_info().lamports()
.checked_sub(amount)
.ok_or(ProgramError::InsufficientFunds)?;
**ctx.accounts.creator.to_account_info().try_borrow_mut_lamports()? =
ctx.accounts.creator.to_account_info().lamports()
.checked_add(amount)
.ok_or(ErrorCode::CalculationOverflow)?;
Ok(())
}
}
