CVE-2026-23498 is a high-severity vulnerability affecting Shopware, an open commerce platform. The flaw arises from a regression related to CVE-2023-2017, which allows an array and array crafted PHP Closure to bypass checks against the allow list for the map(...) override. This vulnerability impacts versions from 6.7.0.0 to before 6.7.6.1 and has been fixed in version 6.7.6.1.
The CVSS score for this vulnerability is 7.2, indicating a high level of severity. The attack vector is network-based with low complexity, requiring high privileges and no user interaction. It poses significant risks to confidentiality, integrity, and availability.
Risk to organizations includes potential unauthorized access and manipulation of data, which could lead to significant operational disruptions and reputational damage.
Organizations should prioritize patching immediately to protect their systems from exploitation. The vulnerability is actively known to have possible exploits, underscoring the urgency for remediation.
The vulnerability has been published as part of security advisories, and organizations are encouraged to review their systems for compliance against the patched version.
Vulnerability Details
This vulnerability allows an attacker to bypass security checks for PHP Closures in Shopware, potentially leading to unauthorized code execution. The CVSS score of 7.2 reflects its high severity, with significant impacts across confidentiality, integrity, and availability.
Affected versions include all Shopware versions from 6.7.0.0 to just before 6.7.6.1. The official description outlines the regression originating from CVE-2023-2017, emphasizing the necessity of upgrading to version 6.7.6.1 or later.
Technical Analysis
The root cause of this vulnerability stems from insufficient validation of PHP Closure objects. As a result, an attacker could exploit this oversight to execute arbitrary code through crafted requests.
The attack vector is network-based, with a low attack complexity. It requires high privileges, meaning that an attacker must already have some level of access to execute successful exploits. User interaction is not required for this vulnerability, which enhances its risk.
The impact of this vulnerability is severe, with potential high confidentiality, integrity, and availability impacts, resulting from unauthorized access and code execution capabilities.
Risk & Impact Analysis
Real-world deployment risk is significant, as the vulnerability allows for exploitation through network access, exposing organizations to immediate threats. The blast radius could affect numerous users and systems if left unaddressed.
Organizations should assess their security posture regarding this vulnerability. The urgency is underscored by the CVSS score of 7.2, indicating a high priority for immediate remediation.
