Affected by this issue is an unknown functionality of the file /api/v1/translations/{lang} of the component Translation Cache/Page Sync. The manipulation of the argument lang with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Grav API plugin (grav-plugin-api) 1.0.40 before 1.0.42 caches a full translation dictionary for every well-formed language code sent to the unauthenticated GET /api/v1/translations/{lang} endpoint, and 1.0.16 before 1.0.42 fails to check target and destination page rules in the sync and batch copy endpoints. Unauthenticated attackers can send small requests that each store about 560 KB to exhaust disk or APCu, while accounts with api.pages.write can overwrite translations or create pages that page-level rules deny.
