A security loophole at internet bank Cahoot briefly allowed customers to access other people's accounts.
The website, run by Abbey bank, was closed down for 10 hours on Thursday to carry out urgent repairs.
The site has now reopened and the bank says the problem, which was caused by a system upgrade, has been fixed.
Cahoot apologised for the breach, but said hackers would not have been able to move money between accounts.
The investigation, by BBC Breakfast, followed a tip-off from a viewer, who found he could access the site with only a user name.
I believe that we need to look closely at our processes
