Description: In June 2015, the California Office of the Attorney General disclosed a data breach at the **University of California Irvine Medical Center**, where an employee improperly accessed patient records over an extended period—from **June 2011 to March 2015**. The unauthorized access exposed **personal health information (PHI)** of an **unknown number of patients**, though investigations found **no evidence of sensitive data being stolen or misused**. The breach stemmed from internal misconduct, highlighting vulnerabilities in **employee access controls and monitoring protocols**. While the exposed data included patient details, the lack of confirmed theft or external exploitation mitigated some risks. However, the prolonged duration of the breach (nearly **four years**) raised concerns about **compliance with healthcare privacy regulations (e.g., HIPAA)** and the potential for **reputational damage** due to the mishandling of confidential medical records. The incident underscored the need for stricter **audit trails, access restrictions, and employee training** to prevent similar internal breaches in healthcare institutions.
Description: The University of California, Irvine experienced a data breach reported on **May 14, 2014**, involving unauthorized access to its systems. The breach occurred due to computers being infected with a **keystroke logger** between **February 14 and March 27, 2014**, which potentially compromised **personal and unencrypted medical data** of individuals. The exact number of affected individuals remains **unknown**, raising concerns about the exposure of sensitive health information. The attack method suggests a targeted intrusion aimed at harvesting confidential data, likely through malicious software designed to capture keystrokes—including login credentials, medical records, or other personally identifiable information (PII). The breach underscores vulnerabilities in the university’s cybersecurity defenses, particularly in protecting high-risk data like medical records, which are subject to strict regulatory protections (e.g., HIPAA). The incident highlights the risks of **unauthorized data access** in academic institutions handling sensitive information, with potential long-term repercussions for trust, legal compliance, and individual privacy.
Description: An employee of UC Irvine Medical Center unethically viewed thousands of patient records over a four-year period. The incident compromised the personal health information including names, dates of birth, gender, medical record numbers, height, weight, medical center account numbers, allergy information, home address, medical documentation, diagnoses, test orders and results, of 4,859 patients . The center investigated the incident with the help of external security experts and notifies the affected patients.

Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to versions 19.2.16, 20.3.14, and 21.0.1, there is a XSRF token leakage via protocol-relative URLs in angular HTTP clients. The vulnerability is a Credential Leak by App Logic that leads to the unauthorized disclosure of the Cross-Site Request Forgery (XSRF) token to an attacker-controlled domain. Angular's HttpClient has a built-in XSRF protection mechanism that works by checking if a request URL starts with a protocol (http:// or https://) to determine if it is cross-origin. If the URL starts with protocol-relative URL (//), it is incorrectly treated as a same-origin request, and the XSRF token is automatically added to the X-XSRF-TOKEN header. This issue has been patched in versions 19.2.16, 20.3.14, and 21.0.1. A workaround for this issue involves avoiding using protocol-relative URLs (URLs starting with //) in HttpClient requests. All backend communication URLs should be hardcoded as relative paths (starting with a single /) or fully qualified, trusted absolute URLs.
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Uncontrolled Recursion vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft deep ASN.1 structures that trigger unbounded recursive parsing. This leads to a Denial-of-Service (DoS) via stack exhaustion when parsing untrusted DER inputs. This issue has been patched in version 1.3.2.
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Integer Overflow vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft ASN.1 structures containing OIDs with oversized arcs. These arcs may be decoded as smaller, trusted OIDs due to 32-bit bitwise truncation, enabling the bypass of downstream OID-based security decisions. This issue has been patched in version 1.3.2.
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, working with large buffers in Lua scripts can lead to a stack overflow. Users of Lua rules and output scripts may be affected when working with large buffers. This includes a rule passing a large buffer to a Lua script. This issue has been patched in versions 7.0.13 and 8.0.2. A workaround for this issue involves disabling Lua rules and output scripts, or making sure limits, such as stream.depth.reassembly and HTTP response body limits (response-body-limit), are set to less than half the stack size.
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions from 8.0.0 to before 8.0.2, a NULL dereference can occur when the entropy keyword is used in conjunction with base64_data. This issue has been patched in version 8.0.2. A workaround involves disabling rules that use entropy in conjunction with base64_data.
