GHSA-HQRP-M84V-2M2F
Vulnerability from github – Published: 2026-01-15 18:13 – Updated: 2026-01-15 20:17Summary
The API endpoint for listing Predefined Properties in the Pimcore platform lacks adequate server-side authorization checks. Predefined Properties are configurable metadata definitions (e.g., name, key, type, default value) used across documents, assets, and objects to standardize custom attributes and improve editorial workflows, as documented in Pimcore's official properties guide. Testing confirmed that an authenticated backend user without explicit permissions for property management could successfully call the endpoint and retrieve the complete list of these configurations. This exemplifies Broken Access Control (OWASP Top 10 A01:2021), enabling unauthorized access to administrative features and potentially violating role-based access controls inherent to Pimcore's multi-user environment.
Details
The backend user without permission was still able to list "Predefined Properties" item
Step to Reproduce the issue
login as Admin (full permission) and clicked "Predefined Properties"
Then, captured and saved the request:
- List API
Next, login a backend user with no permission
The copy the "Cookie" and "X-Pimcore-Csrf-Token"
After that, pasted the copied "Cookie" and "X-Pimcore-Csrf-Token" to captured request
-List API
Impact
Exploitation allows low-privileged users to enumerate all Predefined Properties, exposing internal metadata schemas, default values, and configuration details that may reveal business logic, data classification strategies, or sensitive defaults (e.g., proprietary keys or select options). In a PIM system like Pimcore, this could facilitate reconnaissance for further attacks, such as targeted data manipulation or privilege escalation, leading to unauthorized alterations of asset/object properties. For organizations handling regulated content (e.g., e-commerce catalogs under GDPR or PCI DSS), such exposure risks compliance breaches, intellectual property leakage, and operational inconsistencies from unintended property overrides.

GHSA-HR7J-63V7-VJ7G
Vulnerability from github – Published: 2026-02-17 17:15 – Updated: 2026-02-17 17:15Summary
Deleting a user account with SFTP access or changing the user's password does not immediately terminate existing SFTP sessions, allowing continued filesystem access after credentials are revoked. This can result in unintended and unauthorized access to server files even after administrators believe access has been fully invalidated.
Details
When a user with SFTP access is deleted from the Pterodactyl Panel or when the user's password is changed while one or more SFTP connections are active, those existing connections remain fully functional.
Neither account deletion nor password change invalidates the authentication state of already-established SFTP sessions. As a result, the active SFTP connection pool continues to allow read and write operations until the client disconnects or the session times out.
This behavior occurs even when the password is changed by an administrator through the panel, meaning credential rotation does not revoke active access.
This suggests that active SFTP sessions are not tracked or forcefully terminated on credential revocation events. This effectively prevents administrators from responding to credential compromise incidents in real time.
PoC
Scenario 1: Account deletion 1. Create a user with SFTP access to a server. 2. Connect to the server via SFTP using any SFTP client (e.g. sftp, FileZilla). 3. Keep the SFTP session open and active. 4. Delete the user account from the Pterodactyl Panel. 5. Continue performing file operations through the already-established SFTP connection.
Result: The SFTP session remains active and usable despite the user account being deleted.
Scenario 2: Password change 1. Create a user with SFTP access to a server. 2. Establish an active SFTP connection. 3. Change the user's password (including via administrator panel). 4. Continue performing file operations using the existing SFTP connection.
Result: The SFTP session remains active and usable even after the password has been changed.
Impact

"details": "### Summary\nDeleting a user account with SFTP access or changing the user\u0027s password does not immediately terminate existing SFTP sessions, allowing continued filesystem access after credentials are revoked.\nThis can result in unintended and unauthorized access to server files even after administrators believe access has been fully invalidated.\n\n\n### Details\nWhen a user with SFTP access is deleted from the Pterodactyl Panel or when the user\u0027s password is changed while one or more SFTP connections are active, those existing connections remain fully functional.\n\nNeither account deletion nor password change invalidates the authentication state of already-established SFTP sessions. As a result, the active SFTP connection pool continues to allow read and write operations until the client disconnects or the session times out.\n\nThis behavior occurs even when the password is changed by an administrator through the panel, meaning credential rotation does not revoke active access.\n\nThis suggests that active SFTP sessions are not tracked or forcefully terminated on credential revocation events. This effectively prevents administrators from responding to credential compromise incidents in real time.\n\n\n### PoC\nScenario 1: Account deletion\n1. Create a user with SFTP access to a server.\n2. Connect to the server via SFTP using any SFTP client (e.g. sftp, FileZilla).\n3. Keep the SFTP session open and active.\n4. Delete the user account from the Pterodactyl Panel.\n5. Continue performing file operations through the already-established SFTP connection.\n\nResult:\nThe SFTP session remains active and usable despite the user account being deleted.\n\nScenario 2: Password change\n1. Create a user with SFTP access to a server.\n2. Establish an active SFTP connection.\n3. Change the user\u0027s password (including via administrator panel).\n4. Continue performing file operations using the existing SFTP connection.\n\nResult:\nThe SFTP session remains active and usable even after the password has been changed.\n\n\n### Impact\nThis issue prevents immediate revocation of compromised credentials.

Mitigation MIT-1
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Mitigation MIT-46
Strategy: Separation of Privilege
- Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
CAPEC-19: Embedding Scripts within Scripts
An adversary leverages the capability to execute their own script by embedding it within other scripts that the target software is likely to execute due to programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts.
CAPEC-441: Malicious Logic Insertion
An adversary installs or adds malicious logic (also known as malware) into a seemingly benign component of a fielded system. This logic is often hidden from the user of the system and works behind the scenes to achieve negative impacts. With the proliferation of mass digital storage and inexpensive multimedia devices, Bluetooth and 802.11 support, new attack vectors for spreading malware are emerging for things we once thought of as innocuous greeting cards, picture frames, or digital projectors. This pattern of attack focuses on systems already fielded and used in operation as opposed to systems and their components that are still under development and part of the supply chain.
CAPEC-478: Modification of Windows Service Configuration
An adversary exploits a weakness in access control to modify the execution parameters of a Windows service. The goal of this attack is to execute a malicious binary in place of an existing service.
CAPEC-479: Malicious Root Certificate
An adversary exploits a weakness in authorization and installs a new root certificate on a compromised system. Certificates are commonly used for establishing secure TLS/SSL communications within a web browser. When a user attempts to browse a website that presents a certificate that is not trusted an error message will be displayed to warn the user of the security risk. Depending on the security settings, the browser may not allow the user to establish a connection to the website. Adversaries have used this technique to avoid security warnings prompting users when compromised systems connect over HTTPS to adversary controlled web servers that spoof legitimate websites in order to collect login credentials.
CAPEC-502: Intent Spoof
An adversary, through a previously installed malicious application, issues an intent directed toward a specific trusted application's component in an attempt to achieve a variety of different objectives including modification of data, information disclosure, and data injection. Components that have been unintentionally exported and made public are subject to this type of an attack. If the component trusts the intent's action without verififcation, then the target application performs the functionality at the adversary's request, helping the adversary achieve the desired negative technical impact.
CAPEC-503: WebView Exposure
An adversary, through a malicious web page, accesses application specific functionality by leveraging interfaces registered through WebView's addJavascriptInterface API. Once an interface is registered to WebView through addJavascriptInterface, it becomes global and all pages loaded in the WebView can call this interface.
CAPEC-536: Data Injected During Configuration
An attacker with access to data files and processes on a victim's system injects malicious data into critical operational data during configuration or recalibration, causing the victim's system to perform in a suboptimal manner that benefits the adversary.
CAPEC-546: Incomplete Data Deletion in a Multi-Tenant Environment
An adversary obtains unauthorized information due to insecure or incomplete data deletion in a multi-tenant environment. If a cloud provider fails to completely delete storage and data from former cloud tenants' systems/resources, once these resources are allocated to new, potentially malicious tenants, the latter can probe the provided resources for sensitive information still there.
CAPEC-550: Install New Service
When an operating system starts, it also starts programs called services or daemons. Adversaries may install a new service which will be executed at startup (on a Windows system, by modifying the registry). The service name may be disguised by using a name from a related operating system or benign software. Services are usually run with elevated privileges.
CAPEC-551: Modify Existing Service
When an operating system starts, it also starts programs called services or daemons. Modifying existing services may break existing services or may enable services that are disabled/not commonly used.
CAPEC-552: Install Rootkit
An adversary exploits a weakness in authentication to install malware that alters the functionality and information provide by targeted operating system API calls. Often referred to as rootkits, it is often used to hide the presence of programs, files, network connections, services, drivers, and other system components.
CAPEC-556: Replace File Extension Handlers
When a file is opened, its file handler is checked to determine which program opens the file. File handlers are configuration properties of many operating systems. Applications can modify the file handler for a given file extension to call an arbitrary program when a file with the given extension is opened.
CAPEC-558: Replace Trusted Executable
An adversary exploits weaknesses in privilege management or access control to replace a trusted executable with a malicious version and enable the execution of malware when that trusted executable is called.
CAPEC-562: Modify Shared File
An adversary manipulates the files in a shared location by adding malicious programs, scripts, or exploit code to valid content. Once a user opens the shared content, the tainted content is executed.
CAPEC-563: Add Malicious File to Shared Webroot
An adversaries may add malicious content to a website through the open file share and then browse to that content with a web browser to cause the server to execute the content. The malicious content will typically run under the context and permissions of the web server process, often resulting in local system or administrative privileges depending on how the web server is configured.
CAPEC-564: Run Software at Logon
Operating system allows logon scripts to be run whenever a specific user or users logon to a system. If adversaries can access these scripts, they may insert additional code into the logon script. This code can allow them to maintain persistence or move laterally within an enclave because it is executed every time the affected user or users logon to a computer. Modifying logon scripts can effectively bypass workstation and enclave firewalls. Depending on the access configuration of the logon scripts, either local credentials or a remote administrative account may be necessary.
CAPEC-578: Disable Security Software
An adversary exploits a weakness in access control to disable security tools so that detection does not occur. This can take the form of killing processes, deleting registry keys so that tools do not start at run time, deleting log files, or other methods.
