Security readout for executives and security teams
Plain-English summary
CVE-2026-23498 affects Shopware 6.7.0.0 through versions before 6.7.6.1. It is a high-severity code-generation control flaw in Twig-rendered views. Successful abuse could compromise confidentiality, integrity, and availability, but the CVSS data indicates the attacker needs high privileges.
Executive priority
Treat as a prompt patching item for affected Shopware environments, especially revenue-generating storefronts. It is not currently documented as exploited, but the potential business impact is high if a privileged account is abused.
Technical view
Shopware describes this as a regression of CVE-2023-2017. An array and array-crafted PHP Closure were not checked against the allow list for the map(...) override in Twig-rendered views. The issue is classified as CWE-94 and fixed in Shopware 6.7.6.1.
Likely exposure
Exposure is limited to Shopware installations running versions >= 6.7.0.0 and < 6.7.6.1. The CVSS vector is network-accessible with low attack complexity, no user interaction, and high privileges required.
Exploitation context
The provided sources do not report active exploitation, and this CVE is not marked in KEV. The high-privilege requirement reduces broad opportunistic risk, but compromise of privileged Shopware access could make impact severe.
Researcher notes
The public record identifies the vulnerable range, fix version, CWE-94 classification, and fixing commit. Available evidence does not include exploit details or proof of active exploitation. Further analysis should focus on the allow-list check regression around Twig map(...) override handling.
Mitigation direction
- Upgrade affected Shopware installations to 6.7.6.1 or later.
- Review the Shopware security advisory for any deployment-specific guidance.
- Prioritize stores with privileged admin access exposed to larger user populations.
- Restrict and monitor privileged Shopware accounts until patching is complete.
Validation and detection
- Inventory Shopware instances and record exact running versions.
- Confirm no instance runs >= 6.7.0.0 and < 6.7.6.1.
- Verify the 6.7.6.1 fix is present after upgrade.
- Review privileged account activity around Twig/template or view-related changes.

Improper Control of Generation of Code ('Code Injection')
Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
