The application passes the raw filename to a system unzip command, enabling shell metacharacters to execute arbitrary commands on the host. An attacker can therefore achieve full compromise of the server running Koha, with consequences for confidentiality, integrity, and availability of the library system and any connected services.", "risk_and_exploitability": "The CVSS score of 9.8 indicates Critical severity, while the EPSS score of under 1% suggests a low probability of exploitation in the wild. The vulnerability is not listed as a Known Exploited Vulnerability, meaning no public exploit has yet been reported. A remote attacker can exploit the flaw by uploading a ZIP file with a crafted filename containing shell metacharacters and then invoking the Process Images action. The attack requires the ability to submit uploads, which may be restricted to logged\u2011in users, but even limited accounts can trigger the vulnerability.
