The CVE-2026-23496 describes a medium-severity vulnerability in the Pimcore Web2Print Tools Bundle, which adds tools for web-to-print use cases to Pimcore. The vulnerability arises from the application's failure to enforce proper server-side authorization checks on the API endpoint responsible for managing 'Favourite Output Channel Configurations'. As a result, prior to the versions 5.2.2 and 6.1.1, an authenticated backend user, even without explicit permissions for this feature, could invoke the endpoint to modify or retrieve these configurations.
The CVSS score for this vulnerability is 5.4, categorized as medium severity. This score indicates that the impact on confidentiality and integrity is low, while there is no impact on availability. The attack vector is network-based, requiring low complexity and low privileges to exploit. Given the nature of the vulnerability, it is crucial for organizations using affected versions to apply the patch promptly.
Testing has shown that the vulnerability can potentially allow unauthorized users to exploit the API endpoint, leading to unauthorized access to sensitive configurations. The risk to organizations includes potential data leakage and unauthorized configuration changes, which may affect the application's integrity. Organizations should prioritize patching immediately to mitigate these risks.
The vulnerability has been fixed in versions 5.2.2 and 6.1.1, released on January 30, 2026. With the potential for exploitation, it is critical for users of the affected versions to update their systems as soon as possible.
Given the current status of this vulnerability, organizations are urged to take immediate action to protect their systems from potential exploitation.
Organizations should also consider implementing additional security controls and monitoring to detect any unauthorized access attempts to the affected API endpoint.
Vulnerability Details
The official CVE description states that the application fails to enforce proper server-side authorization checks on the API endpoint responsible for managing 'Favourite Output Channel Configurations'. The vulnerability exists in versions prior to 5.2.2 and 6.1.1, and it is classified under CWE-284 (Improper Access Control) and CWE-863 (Credential Inclusion).
The CVSS score of 5.4 indicates a medium severity, with a network attack vector (AV:N), low attack complexity (AC:L), low privileges required (PR:L), and no user interaction required (UI:N). The impacts on confidentiality and integrity are both rated as low (C:L, I:L) with no impact on availability (A:N).
The vulnerability was published on January 15, 2026, and has since been analyzed and classified for remediation.
Technical Analysis
The root cause of CVE-2026-23496 is the lack of proper authorization checks on the API endpoint, which allows an authenticated user to access functionality that should be restricted based on user permissions. The attack vector is through the network, which means that an attacker could exploit this vulnerability remotely.
The attack complexity is low, as it does not require advanced skills or knowledge to exploit. The privileges required are also low, meaning that even users with minimal access could potentially exploit the vulnerability. User interaction is not required, making it easier for attackers to leverage this flaw without needing any additional actions from the victim.
The confidentiality and integrity impacts are both rated low, indicating that while sensitive data could be accessed or modified, the overall impact on the system's availability is none.
Risk & Impact Analysis
The risk to organizations includes unauthorized access and modification of configurations that could lead to data exposure or system misconfiguration. Given the nature of web-to-print services, this vulnerability could have broader implications for the integrity of printed materials and the management of output channels.
The urgency for organizations to address this vulnerability is significant. With a CVSS score of 5.4, it is classified as medium severity, indicating that organizations should address it in their priority patch cycle. The blast radius could affect multiple configurations within the Pimcore environment, making timely remediation essential.
