High Severity Vulnerabilities Identified in NextGen Healthcare Mirth Connect
Three high-severity vulnerabilities have been identified in NextGen Healthcare Mirth Connect (Mirth Connect), a cross-platform healthcare integration engine for connecting, routing, transforming, and exchanging clinical and administrative data between different healthcare systems. The vulnerabilities are due to improper neutralization of special elements used in SQL commands and improper restriction of XML External Entity Reference. Successful exploitation of the vulnerabilities could allow denial-of-service attacks and data exfiltration. The vulnerabilities were identified by security researcher Abhinav Agarwal using autonomous agents running his published methodology on AI-assisted vulnerability discovery. “Mirth Connect is effectively a switchboard between healthcare systems. It can sit between lab systems, imaging systems, databases, and clinical applications, so a vulnerability in the integration layer can expose much more than one isolated application,” Agarwal told The HIPAA Journal. A potential problem is that healthcare organizations may not know that they have a...
Veradigm Discloses Third Party Data Breach as Hackers Threaten to Publish Data
The Chicago, Illinois-based practice management and electronic health record company Veradigm (formerly Allscripts Healthcare Solutions) has disclosed a cybersecurity incident in a Form 8-K filing with the U.S. Securities and Exchange Commission (SEC). According to the September 8, 2026, filing, Veradigm recently learned that one of its third-party vendors had experienced a cybersecurity incident that impacted a small number of Veradigm’s customers. Veradigm explained that a threat actor obtained credentials from the vendor’s environment for a Veradigm Application Programming Interface (API) used for customer services. The threat actor was able to use the access to copy patient data. The threat actor only had access to the API, and no other parts of its network were compromised, including servers, databases, or other systems. Veradigm determined that data stolen in the incident included the personal information of patients, which for certain patients may have involved their Social Security numbers; however, the company has determined that clinical and medical information was not...
AdaptHealth Data Breach Affects 4.1 Million Individuals
In early July, we reported that AdaptHealth had notified the U.S. Securities and Exchange Commission that it had experienced a cybersecurity incident involving the theft of patient data. At the time of the Form 8-K filing, AdaptHealth had not determined the extent to which patient data was compromised in the incident. The HHS Office for Civil Rights has now been informed that the electronic protected health information of 4,115,802 individuals was compromised in the incident. AdaptHealth added a notice to its website on August 14, 2026, that provided further information on the data compromised in the incident. The notice explains that the forensic investigation determined that the attack occurred on June 5, 2026, and the threat actor exfiltrated files containing names, contact information, demographic information, health insurance information, and health information. AdaptHealth explained that it is unaware of any actual or attempted misuse of that data; however, as a precaution, the affected individuals have been offered complimentary credit monitoring and identity theft...

FBI Raises Alarm About OAuth Consent Phishing Activity
The Federal Bureau of Investigation (FBI) has issued a warning about ongoing phishing activity involving a sophisticated technique known as OAuth consent phishing. Since late 2025, the FBI has observed malicious cyber actors using OAuth consent phishing in targeted attacks on prominent individuals, their family members, and personal acquaintances to gain persistent access to their accounts. Similar to other forms of targeted phishing, the campaign involves impersonation of a trusted entity and tricks the victim into granting access to their account; however, this approach does not require the victim to disclose their username and password. The technique relies on OAuth, a commonly used authorization framework that allows websites and web applications to request access to a user’s account on another application, without exposing their login credentials. With OAuth consent phishing, an attacker creates a malicious application and registers it with a legitimate OAuth provider. The application is configured with high-level privileges, such as the ability to access contacts, read and...
