New cPanel Flaw Lets a Hosting Account With Mail Privileges Run Code as Root

New cPanel Flaw Lets a Hosting Account With Mail Privileges Run Code as Root

Sep 09, 2026 Vulnerability / Web Security
cPanel has patched a flaw that it says lets a single hosting account take control of an entire server. An authenticated account holder with mail-related privileges can create files of their choosing on the server through EmailTrack and, from there, run code as the root user. cPanel published the  advisory on September 8  and says every supported version of cPanel and WHM is affected. The flaw is tracked as CVE-2026-67401 . cPanel's advisory calls it an SQL injection issue in EmailTrack, but does not say which cPanel feature or privilege an account needs. cPanel's developer documentation lists an EmailTrack module that tracks email statistics, and the advisory does not say whether that is the affected code. cPanel is web hosting control panel software. A customer manages one hosting account via cPanel, while the provider manages the entire machine via WHM as the root user. Attackers exploited  a different cPanel flaw in April . Taking over the panel is not the s...
New cPanel Critical Flaw Could Let Hosting Customers Run SQL as Database Root

New cPanel Critical Flaw Could Let Hosting Customers Run SQL as Database Root

Aug 04, 2026 Vulnerability / Database Security
cPanel has patched a flaw that let an authenticated hosting customer execute SQL in the database's root context, crossing the privilege boundary between a cPanel account and the server's administrative database identity. It shipped in a targeted security release that closes two other routes past account boundaries. The database bug is tracked as CVE-2026-58048 (CVSS 4.0 score: 9.4) and affects all supported versions of cPanel & WHM, along with WP Squared. Reaching it requires a valid cPanel account and access to the MySQL/MariaDB feature. From there, the vendor says the account holder could execute arbitrary database commands with full administrative privileges. Depending on the operating system and database engine configuration, “this may extend to operating-system-level compromise.” cPanel patched CVE-2026-58048 in these builds: 11.110.0.137 11.118.0.71 11.126.0.78 11.134.0.48 11.136.0.32 138.1.6 for WP Squared Servers that cannot update immediately can ...

LiteSpeed Enterprise Flaw Could Let One Hosting Account Gain Root Access on a Shared Server

LiteSpeed Enterprise Flaw Could Let One Hosting Account Gain Root Access on a Shared Server

Sep 15, 2026 Vulnerability / Web Security
A critical vulnerability in LiteSpeed Web Server Enterprise could let a low-privilege website user gain root access on a shared-hosting server, cPanel warned in an  advisory published on September 14 . On such servers, many customers' sites run on a single machine, and an attacker with one of those hosting accounts could exploit the flaw to access or alter other sites and the server itself, according to the advisory. cPanel said it had received notice of the flaw, which affects versions before 6.3.7, and urged administrators to update to that release, which LiteSpeed  published on September 11 . The flaw can bypass the controls that keep hosting accounts apart, including  CageFS , cPanel said. CageFS is a CloudLinux tool that gives each hosting account a restricted view of the file system, so it cannot see other accounts or the server's configuration files. Neither cPanel's advisory nor LiteSpeed's release notes describe how the flaw works. LiteSpeed's an...

Security researcher David Strydom has been credited with discovering and reporting the flaw. LiteSpeed noted that the "vulnerability is being actively exploited," but refrained from sharing additional details. It has provided the following indicator of compromise - grep -rE "cpanel_jsonapi_func=redisAble...
2-Factor Authentication Bypass Flaw Reported in cPanel and WHM Software

2-Factor Authentication Bypass Flaw Reported in cPanel and WHM Software

Nov 25, 2020
cPanel, a provider of popular administrative tools to manage web hosting, has patched a security vulnerability that could have allowed remote attackers with access to valid credentials to bypass two-factor authentication (2FA) protection on an account. The issue, tracked as "SEC-575" and discovered by researchers from  Digital Defense , has been remedied by the company in versions 11.92.0.2, 11.90.0.17, and 11.86.0.32 of the software. cPanel and WHM (Web Host Manager) offers a Linux-based control panel for users to handle website and server management, including tasks such as adding sub-domains and performing system and control panel maintenance. To date, over  70 million domains  have been launched on servers using cPanel's software suite. The issue stemmed from a lack of rate-limiting during 2FA during logins, thus making it possible for a malicious party to repeatedly submit 2FA codes using a brute-force approach and circumvent the authentication check. Digital D...
