CVE-2026-55212
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk10th percentile - higher than 10% of all known CVEs
Summary
In Pimcore before versions 2025.4.6 and 2026.1.6, the Studio API class definition creation endpoint was guarded by the 'objects' permission instead of 'classes', allowing editor-level users to create class definitions without admin privileges. Missing UID format validation in the API layer allowed malformed UIDs to reach model-layer validation and expose internal exceptions.
Risk Assessment
The organization is at risk of unauthorized class definition creation, which can generate new database tables and PHP files on the server, potentially destabilizing the system and leaking sensitive information through internal errors.
Recommendation
Immediately upgrade Pimcore to version 2025.4.6 or 2026.1.6, which include security fixes. After updating, review user permissions and configure appropriate access controls.
Other vulnerabilities in Pimcore
See all- CVE-2026-5394High
An authenticated administrative user who can import or save DataObject class definitions can inject attacker-controlled composite index metadata, leading to unintended SQL execution in the backend.
- CVE-2026-23493High
Pimcore is an open source data and experience management platform. Prior to versions 12.3.1 and 11.5.14, the http_error_log file stores the $_COOKIE and $_SERVER variables, which means sensitive information such as database passwords, cookie session data, and other details can be accessed or recovered through the Pimcore backend.
- CVE-2026-23492High
Pimcore is an Open Source Data & Experience Management Platform. Prior to 12.3.1 and 11.5.14, an incomplete SQL injection patch in the Admin Search Find API allows an authenticated attacker to perform blind SQL injection. Although CVE-2023-30848 attempted to mitigate SQL injection by removing SQL comments (--) and catching syntax errors, the fix is insufficient. Attackers can still inject SQL payloads that do not rely on comments and infer database information via blind techniques. This vulnerability affects the admin interface and can lead to database information disclosure. This vulnerability is fixed in 12.3.1 and 11.5.14.
- CVE-2015-4426High
SQL injection vulnerability in pimcore before build 3473 allows remote attackers to execute arbitrary SQL commands via the filter parameter to admin/asset/grid-proxy.
- CVE-2026-55634Critical
Pimcore prior to versions 11.5.19, 12.3.10, and 2026.1.6 has a vulnerability in the class-definition import endpoint where a DataObject field name is emitted without an identifier allowlist, allowing an authenticated user with objects permission to inject PHP syntax into generated DataObject classes and inject SQL identifier content into schema-changing statements. The setName() validation did not reject semicolons, braces, backticks, spaces, or other non-identifier characters.
- CVE-2026-55220Critical
Pimcore before versions 11.5.19, 12.3.10, and 2026.1.6 has a vulnerability in Hotspotimage::getDataFromResource() that passes the __hotspots column to Pimcore\Tool\Serialize::unserialize() without an allowed-classes restriction after JSON decoding fails. An attacker with the ability to write crafted PHP serialized bytes into that column can instantiate available classes and trigger magic methods, potentially leading to arbitrary file writes or code execution. This issue is fixed for Hotspotimage in versions 11.5.19, 12.3.10, and 2026.1.6.
- CVE-2026-45704High
Pimcore before versions 11.5.17 (LTS) and 12.3.6 has inconsistent authorization between the report listing and report detail endpoints in CustomReports. A low-privileged backend user with the 'reports' permission can read an unshared report by name, accessing metadata, data source configuration, and sharing settings.
- CVE-2026-45260High
Vulnerability in Pimcore before versions 11.5.17 (LTS) and 12.3.7. The WebDAV endpoint `/asset/webdav{path}` allows MOVE operation without authentication, enabling an unauthorized attacker to delete, move, or overwrite assets.
- CVE-2026-44739High
Pimcore prior to versions 11.5.17 (LTS) and 12.3.6 contains an SQL injection vulnerability in the columnConfigAction endpoint. An attacker with reports_config permission can execute arbitrary SELECT queries, use UNION statements, dangerous database functions, and error-based SQL injection to exfiltrate or manipulate data.
- CVE-2026-45703Medium
Pimcore prior to versions 11.5.17 (LTS) and 12.3.7 has a vulnerability in the WordExport export flow. It only checks the word_export feature permission and directly resolves attacker-controlled type/id input without enforcing view permission on page, snippet, email, or object elements, allowing a low-privileged backend user to export document content the user is not allowed to view.
Original NVD description (English source)
Pimcore is an Open Source Data & Experience Management Platform. Prior to 2025.4.6 and 2026.1.6, the Studio API class definition creation endpoint POST /pimcore-studio/api/class/definition/configuration-view/detail/create is guarded by the objects permission instead of the classes permission, allowing a standard editor-level user to create class definitions without admin privileges. Class definition creation generates new database tables and PHP class files on the server, and missing API-layer UID format validation allows malformed UIDs to reach model-layer validation and return internal exceptions. This issue is fixed in versions 2025.4.6 and 2026.1.6.
