ZDI-26-215: KeePassXC OpenSSL Configuration Uncontrolled Search Path Element Local Privilege Escalation Vulnerability
This vulnerability allows local attackers to escalate privileges on affected installations of KeePassXC. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The ZDI has assigned a CVSS rating of 7.3. The following CVEs are assigned: CVE-2026-4158.
AI Analysis
Technical Summary
CVE-2026-4158 is a local privilege escalation vulnerability in KeePassXC caused by loading OpenSSL configuration from an unsecured location. This uncontrolled search path element allows an attacker who already has low-privileged code execution on the system to escalate privileges by executing arbitrary code within the KeePassXC context. The vulnerability has a CVSS score of 7.3 (AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H). KeePassXC has released a security update to fix this issue.
Potential Impact
Exploitation of this vulnerability allows a local attacker with limited code execution capabilities to escalate privileges and execute arbitrary code with the privileges of the KeePassXC process. This can lead to full compromise of the affected user's environment and potentially access to sensitive password database information.
Mitigation Recommendations
KeePassXC has issued an official update that corrects this vulnerability. Users should apply the update provided by KeePassXC as soon as possible to remediate this issue. No additional mitigation steps are indicated beyond applying the vendor's fix.
