Improper authorization checks of team members privileges allow a team member to escalate privileges to the team owner account.

Improper sanitization of the `status` query parameter of the `/unprotected/nova_error` endpoint allows unauthenticated attacker to inject arbitrary HTTP header to the response.

Incorrect privileges management and insufficient path filtering allow to read arbitrary file on the server via the cpdavd attachment download endpoints.

Insufficient sanitization of SQL queries in the `sqloptimizer` utility script allows SQL Injections on behalf of the root user if Slow Query logging is enabled.

SSL verification is disabled in the DNS Cluster system. This could allow for a malicious server to man-in-the-middle the request and capture credentials.

A chmod call in the cPanel Nova plugin's Cpanel::Nova::Connector follows symlinks, allowing setting root permissions on arbitrary system files or directories. That can cause DoS or local privilege escalation when an authenticated cPanel user places a symlink at a user-controlled legacy Nova path under their home directory.

Insufficient input validation of the `plugin` parameter of the `create_user` plugin allows arbitrary Perl code execution on behalf of the already authenticated account's system user.

Insufficient input validation of the feature file name in `feature::LOADFEATUREFILE` adminbin call can cause arbitrary file read when a relative file path is passed.

cPanel and WHM versions prior to 11.110.0.97, 11.118.0.63, 11.126.0.54, 11.132.0.29, 11.134.0.20, and 11.136.0.5 contain an authentication bypass vulnerability in the login flow that allows unauthenticated remote attackers to gain unauthorized access to the control panel.

Cpanel::JSON::XS before version 4.40 for Perl has an integer buffer overflow causing a segfault when parsing crafted JSON, enabling denial-of-service attacks or other unspecified impact
