# CVE-2024-42354: Shopware vulnerable to Improper Access Control with ManyToMany associations in store-api > Attackers can access unauthorized data via ManyToMany associations in the store-API if custom extensions are used, requiring an upgrade to Shopware. - **Severity:** Medium 5.3 (`CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** A user has to click or open something - **Fix available:** Yes - **Published:** 8 Aug 2024 - **Updated:** 8 Aug 2024 - **Also known as:** GHSA-hhcq-ph6w-494g ## What is CVE-2024-42354? CVE-2024-42354 is a medium-severity missing authorization vulnerability in Shopware Shopware, published on 8 Aug 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link. ### Official description Shopware is an open commerce platform. The store-API works with regular entities and not expose all fields for the public API; fields need to be marked as ApiAware in the EntityDefinition. So only ApiAware fields of the EntityDefinition will be encoded to the final JSON. Prior to versions 6.6.5.1 and 6.5.8.13, the processing of the Criteria did not considered ManyToMany associations and so they were not considered properly and the protections didn't get used. This issue cannot be reproduced with the default entities by Shopware, but can be triggered with extensions. Update to Shopware 6.6.5.1 or 6.5.8.13 to receive a patch. For older versions of 6.2, 6.3, and 6.4, corresponding security measures are also available via a plugin.

Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
