GHSA-7f62-4887-cfv5
HIGHGHSA-7f62-4887-cfv5 is a high-severity (CVSS 8.8) Improper Privilege Management vulnerability in alextselegidis/easyappointments. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-7f62-4887-cfv5 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

alextselegidis/easyappointmentsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
The Easy!Appointments API authorization is checked against the user's existence, without validating the permissions. As a result, a low privileged user (eg. provider) can create a new admin user via the "/api/v1/admins/" endpoint and take over the system. A patch is available on the develop branch of the repository.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for alextselegidis/easyappointments. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of alextselegidis/easyappointments has shipped for GHSA-7f62-4887-cfv5 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-7f62-4887-cfv5 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-7f62-4887-cfv5. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
