Unsecured API at private NHS provider left NHS patient data vulnerable

The NHS is investigating allegations that patient data was vulnerable to hacking due to a software flaw at Medefer, a private medical services company handling NHS referrals. In November, a software engineer discovered a flaw affecting the company's internal patient record system, involving an unsecured API, potentially allowing unauthorised access to patient information, which he claims could have existed for six years. 

Medefer disputes this claim and maintains that no patient data was compromised and that the flaw was fixed immediately upon discovery. The company commissioned an external security agency to review its systems, which found no evidence of a data breach. Medefer also reported the issue to the Information Commissioner's Office (ICO) and Care Quality Commission (CQC), with the ICO confirming no further action was required due to the lack of evidence of a breach.
