Real-World Exposure
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
alextselegidis/easyappointments is vulnerable to session fixation. The application does not generate a new ea_session cookie after the user authenticates. A malicious user may create a new session cookie value and inject it to a victim. After the victim logs in, the injected cookie becomes valid, giving the attacker access to the user's account through the active session. If an attacker conducts this attack against an admin user, the attacker may escalate their privileges with the admin user being unaware.
This issue is patched in commit 7f37350fab9d729a9350d96369ff0f453cf7b840 and anticipated to be part of version 1.5.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for alextselegidis/easyappointments, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of alextselegidis/easyappointments for CVE-2023-2105. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
