CVE-2026-108390

CWE-88 Oct 14, 2026
HestiaCP Low-Privileged User to Root via Config-Field Injection and PATH Hijacking
Hestia Control Panel is a lightweight and powerful control panel for the modern web. From version 1.9.7 through 1.10.4, update_object_value() in func/main.sh does not escape single quotes when writing a custom document-root value to a user's web.conf file, allowing a low-privileged authenticated panel user with a web domain to inject an additional PATH field. When the user invokes the ordinary Search feature, the root-privileged v-search-user-object script loads the forged field through parse_object_kv_list_non_eval(), which permits reserved shell-variable names and globally replaces PATH before invoking column without an absolute path. By placing a malicious column executable in the injected search path, the user can execute arbitrary code as root. This residual vulnerability was introduced when version 1.9.7 replaced the raw eval sink addressed by CVE-2026-84984 with parse_object_kv_list_non_eval(), and it is fixed in version 1.10.5.

CWE-79 Jul 10, 2026
Cross-site Scripting (XSS) in Hestiacp Control Panel
HestiaCP before 1.9.5 contains a stored cross-site scripting vulnerability that allows authenticated low-privilege users to inject arbitrary HTML by creating a DNS record with a double-quote followed by a script payload in the value field. The application fails to apply htmlspecialchars() encoding to the DNS record value field rendered into the data-sort-value HTML attribute in list_dns_rec.php, allowing the payload to execute in the browser of any user who views the DNS record list, including administrators.

CWE-78 Jul 10, 2026
OS Command Injection in Hestiacp Control Panel
HestiaCP before 1.9.5 contains an authenticated OS command injection vulnerability that allows low-privilege authenticated users to execute arbitrary commands as root by injecting a single-quote character into unvalidated DNS record types. Attackers can exploit insufficient input validation in is_dns_record_format_valid() combined with unsafe eval-based parsing in update_domain_zone() to prematurely close a variable assignment string and achieve full root code execution on the underlying host in a single DNS record creation step.
CVE-2026-12196
High · 8.3
CWE-287 Jul 4, 2026
HestiaCP Admin Takeover
HestiaCP panel cronjob feature is affected by a broken access control vulnerability. Low privilege users can modify the panel cronjob to execute scripts HestiaCP management scripts with passwordless sudo. This could result in the takeover of administrator users in the application and the underlying webserver.
CVE-2026-43634
High · 7.5
CWE-348 May 19, 2026
HestiaCP 1.2.0-1.9.4 IP Spoofing via CF-Connecting-IP Header
HestiaCP versions 1.2.0 through 1.9.4 contain an IP spoofing vulnerability that allows unauthenticated remote attackers to bypass authentication security controls by supplying an arbitrary IP address in the CF-Connecting-IP HTTP header without verifying the request originated from Cloudflare's network. Attackers can exploit this to circumvent fail2ban brute-force protection, bypass per-user IP allowlists, and poison authentication audit logs by spoofing trusted IP addresses on each request.
CVE-2026-43633
Critical · 10.0
CWE-502 May 19, 2026
HestiaCP 1.9.0-1.9.4 Deserialization RCE via Web Terminal
HestiaCP versions 1.9.0 through 1.9.4 contain a deserialization vulnerability in the web terminal component caused by a session format mismatch between PHP and Node.js that allows unauthenticated remote attackers to achieve root-level code execution. Attackers can inject crafted data into HTTP headers that are processed by the PHP session handler but incorrectly deserialized by the Node.js web terminal component as trusted session values, resulting in arbitrary command execution on systems with the web terminal feature enabled.
