Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 27 May 2026
Detectable: no evidence on record.
No public nuclei template indexed

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

If you cannot patch yet, restrict the 'word_export' permission to trusted users only and monitor backend user permissions carefully. Avoid granting 'word_export' permission to users who should not have access to sensitive documents. Follow vendor updates for an official fix or temporary mitigation.

Description

### Summary The `WordExport` export flow only checks whether the current backend user has the feature permission `word_export`. It does not verify access rights on the target element itself. As a result, a low-privileged backend user can export document content even when the user does not have `view` permission on that document. In the local Docker reproduction, a low-privileged user successfully exported sensitive content from a page the user was not allowed to view: - `POC-WORDEXPORT-TITLE` - `POC-WORDEXPORT-DESC` ### Root Cause The controller only performs a feature-level permission check before starting the export flow: - [[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L41)](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L44)#L41) - [TranslationController.php](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L56)#L44) It then directly resolves the target element from attacker-controlled `type/id` input: - [[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L58)](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L56) - [[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L72)](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L113)#L58) For document-like elements such as `Page` and `Snippet`, it renders content in an admin context: - [[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L114)](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L72) - [TranslationController.php](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L113) - [TranslationController.php](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L114) No object-level authorization check such as `isAllowed('view')` is enforced on the target element. ### Affected Scope Based on the source code, the following element types may be affected: - `page` - `snippet` - `email` - `object` For page-like documents, the `pimcore_admin = true` rendering context may expose additional backend-visible content. ### Preconditions - The attacker is an authenticated backend user - The attacker has the `word_export` permission - The attacker does not have `view` permission on the target document ### Reproduction Environment - Reproduction root: `pimcore-12.3.3-repro` - Standalone PoC script: [[poc_wordexport.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3-repro/tools/poc_wordexport.php)](pimcore-12.3.3-repro/tools/poc_wordexport.php) ```php <?php declare(strict_types=1); use Pimcore\Bundle\WordExportBundle\Controller\TranslationController as WordExportController; use Pimcore\Controller\UserAwareController; use Pimcore\Model\Document\Page; use Pimcore\Model\User; use Pimcore\Security\User\TokenStorageUserResolver; use Pimcore\Security\User\User as SecurityUser; use Pimcore\Serializer\Serializer as PimcoreSerializer; use Pimcore\Tool\Authentication; use Symfony\Component\DependencyInjection\ContainerInterface; use Symfony\Component\Filesystem\Filesystem; use Symfony\Component\HttpFoundation\Request; use Symfony\Component\HttpFoundation\RequestStack; use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken; use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorage; require dirname(__DIR__) .

Impact

An authenticated backend user with the 'word_export' permission but without view permission on certain documents can export sensitive document content they are not authorized to see. This leads to unauthorized disclosure of potentially sensitive information. The vulnerability does not affect unauthenticated users and requires the attacker to have backend access with the specific export permission.

CWE-863Incorrect Authorization (opens in a new tab)
Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #17OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
