A change making return routed setterless Collection/Map properties through this unguarded path, so a setterless collection annotated with a restricted is populated from attacker JSON even when the active view excludes it. ## Impact View-restricted (e.g. admin-only) setterless collection/map properties can be written from untrusted JSON despite gating — an access-control / mass-assignment bypass. No RCE or DoS. ## Affected / Patched (verified via ) - 2.21 line: -> fixed in **2.21.4** (backport , #5970) - 3.x line: -> fixed in **3.1.4** (#5969, ) ## Severity / CWE Maintainer: minor.
