Real-World Exposure
shopware/shopwareReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Due to a wrong configuration in the .htaccess file, the configuration file of Javascript dependencies could be read in production environments (themes/package-lock.json). With this information, the used Shopware version might be determined by an attacker, which could be used for further attacks.
Patches
We recommend updating to the current version 5.7.18. You can get the update to 5.7.18 regularly via the Auto-Updater or directly via the release page. https://github.com/shopware5/shopware/releases/tag/v5.7.18
For older versions you can use the Security Plugin: https://store.shopware.com/en/swag575294366635f/shopware-security-plugin.html

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for shopware/shopware, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update shopware/shopware to 5.7.18 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-34098 is resolved across your whole dependency graph.
Workarounds
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
