CVE-2024-42354 | Shopware vulnerable to Improper Access Control with ManyToMany associations in store-api

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.

5.3 3.1 MEDIUM
CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
