CVE-2026-77089 is an authentication bypass vulnerability in the Command Center API of Commvault Cloud. It affects privilege management by allowing unauthorized access through spoofing. The issue is resolved in maintenance releases, and users are advised to update the Command Center software accordingly. The vulnerability has a critical severity rating with a CVSS score of 9.3.
CommServe contained an authorization bypass vulnerability affecting a limited set of command execution operations. Software customers upgrade to resolved maintenance release. Update all Commvault installations, including Commserve, Webserver, Command Center, Media Agents, Clients and HyperScale X.
CommServe contained an allowlist bypass vulnerability affecting command execution authorization. Software customers upgrade to resolved maintenance release. Update all Commvault installations, including Commserve, Webserver, Command Center, Media Agents, Clients and HyperScale X.
A legacy endpoint in Command Center contained an unauthenticated server-side request forgery (SSRF) vulnerability related to the handling of arbitrary target URLs. Software customers upgrade to resolved maintenance release. Update Command Center.
The Report Builder component of the application stores user input directly in a web page and displays it to other users, which raised concerns about a possible Cross-Site Scripting (XSS) attack. Proper management of this functionality helps ensure a secure and seamless user experience. Although the user input is not validated in the report creation, these scripts are not executed when the report is run by end users. The script is executed when the report is modified through the report builder by a user with edit permissions.
The Report Builder is part of the WebConsole. The WebConsole package is currently end of life, and is no longer maintained. We strongly recommend against installing or using it in any production environment. However, if you choose to install it, for example, to access functionality like the Report Builder, it must be deployed within a fully isolated network that has no access to sensitive data or internet connectivity. This is a critical security precaution, as the retired package may contain unpatched vulnerabilities and is no longer supported with updates or fixes.
A security vulnerability has been identified that allows remote attackers to inject or manipulate command-line arguments passed to internal components due to insufficient input validation. Successful exploitation results in a valid user session for a low privilege role.
A security vulnerability has been identified that allows remote attackers to perform unauthorized file system access through a path traversal issue. The vulnerability may lead to remote code execution.
During the brief window between installation and the first administrator login, remote attackers may exploit the default credential to gain admin control. This is limited to the setup phase, before any jobs have been configured.
A vulnerability in a known login mechanism allows unauthenticated attackers to execute API calls without requiring user credentials. RBAC helps limit the exposure but does not eliminate risk.
A DLL injection vulnerability exists in Commvault for Windows 11.20.0, 11.28.0, 11.32.0, 11.34.0, and 11.36.0. During the installation of maintenance updates, an attacker with local access may exploit uncontrolled search path or DLL loading behavior to execute arbitrary code with elevated privileges. The vulnerability has been resolved in versions 11.20.202, 11.28.124, 11.32.65, 11.34.37, and 11.36.15.
