CVE-2023-25575
Secured properties in API Platform Core may be accessible within collections
In short
API Platform Core has a flaw where protected properties in collections can be shown to users who shouldn't see them. The security check is cached after the first item, so it may leak sensitive data if the protection rules depend on item values.
Technical detail
CWE-842 (Improper Neutralization of Persistent Serializable Object Attribute) affects collection endpoints in API Platform Core versions 2.7, 3.0, and 3.1. The security context is evaluated only for the first collection item and then cached globally, causing subsequent items to bypass property-level access controls. Attackers can access properties marked as secured within collection responses when serialization formats other than JSON-LD are used.
Summary generated and translated by AI from the official description.
API Platform Core is the server component of API Platform: hypermedia and GraphQL APIs. Resource properties secured with the `security` option of the `ApiPlatform\Metadata\ApiProperty` attribute can be disclosed to unauthorized users. The problem affects most serialization formats, including raw JSON, which is enabled by default when installing API Platform. Custom serialization formats may also be impacted. Only collection endpoints are affected by the issue, item endpoints are not. The JSON-LD format is not affected by the issue. The result of the security rule is only executed for the first item of the collection. The result of the rule is then cached and reused for the next items. This bug can leak data to unauthorized users when the rule depends on the value of a property of the item. This bug can also hide properties that should be displayed to authorized users. This issue impacts the 2.7, 3.0 and 3.1 branches. Please upgrade to versions 2.7.10, 3.0.12 or 3.1.3. As a workaround, replace the `cache_key` of the context array of the Serializer inside a custom normalizer that works on objects if the security option of the `ApiPlatform\Metadata\ApiProperty` attribute is used.
