Immediately update HestiaCP to the latest version and restrict user permissions for the cronjob feature, applying the principle of least privilege.
Other vulnerabilities in HestiaCP
See all- CVE-2026-43633Critical
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. This allows unauthenticated remote attackers to achieve root-level code execution by injecting crafted data into HTTP headers.
- CVE-2025-30008Medium
HestiaCP before version 1.9.5 has a stored cross-site scripting vulnerability. Authenticated low-privilege users can inject arbitrary HTML/JavaScript by creating a DNS record with a double quote and script payload in the value field. The application fails to encode the value with htmlspecialchars() in list_dns_rec.php, allowing the payload to execute in browsers of other users, including administrators.
- CVE-2025-30007High
HestiaCP before version 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_dns_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-2026-43634High
HestiaCP versions 1.2.0 through 1.9.4 have 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 header without verifying the request originated from Cloudflare.
