AI Analysis
Technical Summary
CVE-2026-91102 is an OS command injection vulnerability (CWE-78) in HP Linux Imaging and Printing Software (HPLIP) versions before 3.26.6. It arises from improper neutralization of special elements used in OS commands, potentially enabling attackers to execute arbitrary commands. The vulnerability has a CVSS 4.0 base score of 8.4, reflecting high impact with local attack vector, low complexity, no privileges required, but user interaction needed. Successful exploitation could lead to remote code execution, privilege escalation, denial of service, information disclosure, or unauthorized file modification. HP has publicly acknowledged and remediated these issues in HPLIP.
Potential Impact
The vulnerability allows an attacker with local access and user interaction to execute arbitrary OS commands, potentially leading to remote code execution, privilege escalation, denial of service, information disclosure, or unauthorized file modification. This can compromise system integrity and confidentiality on affected systems running vulnerable HPLIP versions.
Mitigation Recommendations
HP has remediated this vulnerability in HPLIP version 3.26.6. Users should upgrade to version 3.26.6 or later to address this issue. Since this is not a cloud service, remediation requires applying the official patch or update provided by HP. No known exploits are currently reported in the wild.
