Vulnerability details
The vulnerability allows a low-privileged authenticated user to poison another user's export artifact in eLabFTW by writing attacker-controlled content.
The vulnerability exists due to improper restriction of ZIP entry paths during ELN import, allowing ../ traversal outside the intended per-import extraction directory.
