CVE-2026-92762 in panel
Summary
by MITRE • 09/16/2026
Pelican Panel versions before 1.0.0-beta35 enforce startup write permissions only through disabled form controls rather than server-side authorization checks. Attackers with startup.read permission can craft Livewire state updates to invoke afterStateUpdated callbacks and modify startup commands, docker images, and variables to execute arbitrary commands in the container.

The vulnerability identified in Pelican Panel versions prior to 1.0.0-beta35 represents a critical failure in server-side authorization logic, specifically within the application's initialization and configuration management subsystems. The core issue stems from an over-reliance on client-side controls for enforcing security boundaries during the startup phase of the panel. Instead of implementing robust backend validation to verify that the requesting user possesses the necessary privileges to modify system-level configurations, the software defaults to disabling form elements in the user interface when permissions are insufficient. This approach creates a significant trust boundary violation because it assumes that hiding or disabling UI components effectively prevents unauthorized actions, ignoring the reality that modern web applications allow clients to manipulate state and send arbitrary requests directly to the server API endpoints.
From a technical perspective, this flaw allows attackers who hold even minimal startup.read permissions to escalate their privileges through Livewire framework mechanisms. The vulnerability is exploited by crafting malicious Livewire state updates that trigger afterStateUpdated callbacks on the server side. These callbacks are designed to handle dynamic UI changes but, in this context, they inadvertently expose endpoints for modifying critical container configuration parameters such as startup commands, Docker images, and environment variables. Because there is no corresponding server-side check to validate whether the user initiating these state updates has write access to these specific resources, an attacker can inject arbitrary shell commands or alter container definitions without authorization. This effectively bypasses the intended permission model, turning a read-only role into one with full administrative control over the underlying infrastructure.
The operational impact of this vulnerability is severe, as it leads directly to Remote Code Execution (RCE) within the Docker containers managed by Pelican Panel. By modifying startup commands or environment variables, an attacker can execute arbitrary code with the privileges assigned to the container process. This compromises not only the integrity and confidentiality of the applications running inside these containers but also poses a risk to the host system if privilege escalation techniques are employed within the containerized environment. The ability to change Docker images further allows for persistent access or the introduction of malicious software, effectively giving an attacker full control over the virtualized infrastructure associated with that panel instance. This level of compromise undermines the isolation guarantees provided by containerization and can lead to broader network infiltration if lateral movement is possible from the compromised containers.
This vulnerability aligns closely with CWE-284 Improper Access Control, as it involves a failure to enforce proper authorization policies on sensitive operations. Additionally, it reflects aspects of CWE-915 Improper Modification of Dynamically-Controlled Code Objects, since the attacker modifies configuration objects that dictate code execution behavior at startup. In terms of offensive security frameworks, this attack vector corresponds to ATT&CK technique T1078 Valid Accounts, where an authenticated user exploits insufficient access controls, and potentially T1609 Container Administration, which involves modifying container configurations to maintain persistence or execute commands. The reliance on client-side enforcement rather than server-side validation is a common pitfall in modern web development that underscores the necessity of defense-in-depth strategies for security-critical operations.
To mitigate this vulnerability, immediate updates to Pelican Panel version 1.0.0-beta35 or later are required, as these versions address the authorization logic flaws by implementing proper server-side checks for all configuration modifications. In environments where upgrading is not immediately feasible, administrators should restrict network access to the panel's API endpoints and ensure that only trusted users have startup.read permissions. Furthermore, adopting a principle of least privilege across all user roles can limit the blast radius if such an exploit were attempted in other contexts. It is also recommended to audit Livewire component implementations to ensure that state updates triggering sensitive backend operations are always validated against explicit server-side permission policies rather than relying on UI states or client-supplied data for access decisions. Regular security audits focusing on authorization logic and input validation will help prevent similar misconfigurations in future development cycles.
