Submission Details
Severity:
Deadline Can Be Modified Repeatedly Due to Logic Error
Summary
The set_deadline function fails to update dealine_set, allowing creators to repeatedly change the deadline.
Vulnerability Details
The dealine_set flag is never set to true after the deadline is initialized, allowing multiple calls to set_deadline.
pub fn set_deadline(ctx: Context<FundSetDeadline>, deadline: u64) -> Result<()> {
let fund = &mut ctx.accounts.fund;
if fund.dealine_set { // Typo: should be 'deadline_set'
return Err(ErrorCode::DeadlineAlreadySet.into());
}
fund.deadline = deadline;
// Missing: fund.deadline_set = true;
Ok(())
}
Impact
Creators can extend deadlines indefinitely, preventing contributors from claiming refunds.
