Craft CMS versions before 5.10.11 contain a site scope bypass vulnerability in GraphQL entry mutation resolvers that fail to validate siteId through ArgumentManager::prepareArguments(). Attackers with tokens scoped to one site can read, modify, or delete entries across unauthorized sites by passing siteId directly in mutation arguments.

——0Jenkins Microsoft Entra ID (previously Azure AD) Plugin 710.v0b_ff8e9cc2d2 and earlier grants Entra group permissions using both the group's unique object ID and its display name, allowing attackers who can create an Entra group with a colliding display name to gain the permissions configured for a privileged group.21hCVE-2026-79990——
——0Craft CMS GraphQL entry mutation resolvers (saveEntry, deleteEntry) read siteIddirectly from$argumentswithout passing throughArgumentManagerprepareArguments(), which is the function that enforces site-scope filtering via array_intersect against the GraphQL schema’s allowed sites. The query path (ElementResolverprepareElementQuery) correctly calls prepareArguments()`, so queries to unauthorized sites return empty. But mutations bypass this entirely — an attacker with a token scoped to Site A can create, modify, or delete entries in Site B by passing siteId in the mutations argument.20hCVE-2026-143263.8 LOW—
