Summary
Exposure of Private Personal Information to an Unauthorized Actor in alextselegidis/easyappointments
The software is a booking management system that has a public form to place bookings, and a private area for the calendar and management of services, users, settings, etc. There is a backend API that allows data manipulation, including listing the appointments for a specific time range. This happens on this endpoint: /index.php/backend_api/ajax_get_calendar_events Unfortunately, there is no authentication / permissions-check on that endpoint, the only required parameters in a POST request are "startDate", "endDate" and "csrfToken". Because the csrfToken can be obtained by any unauthenticated user just visiting the public form (and is valid for the backend as well), any attacker can query the backend API and obtain all sorts of private information about the appointment, in JSON format.
Impact
The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions. Typical impact: unauthorized data access or execution of privileged operations.
CVE-2022-0482 has a CVSS score of 9.1 (Critical). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.4.3); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2022-0482? CVE-2022-0482 is a critical-severity incorrect authorization vulnerability in alextselegidis/easyappointments (composer), affecting versions < 1.4.3. It is fixed in 1.4.3. The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions.
- How severe is CVE-2022-0482? CVE-2022-0482 has a CVSS score of 9.1 (Critical). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of alextselegidis/easyappointments are affected by CVE-2022-0482? alextselegidis/easyappointments (composer) versions < 1.4.3 is affected.
- Is there a fix for CVE-2022-0482? Yes. CVE-2022-0482 is fixed in 1.4.3. Upgrade to this version or later.
- Is CVE-2022-0482 exploitable, and should I be worried? Whether CVE-2022-0482 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2022-0482 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2022-0482? Upgrade
