TORONTO - Toronto's Ryerson University is notifying hundreds of students that their personal information was potentially exposed online because of a software error.

The school says the private information of some 588 students, including name, social insurance number, date of birth, student number, mailing and email address, was likely available to be viewed.

The university learned of the hole in their electronic administration system after three students contacted them about what they had discovered.

An investigation found that up to 363 people may have seen the data while electronically registering for courses between Nov. 17 and Jan. 9.

Ryerson installed a software patch to address the error in early January, which the institution says has now fixed the vulnerability.

Officials say they don't believe there has been any misuse of the information that was exposed.
