> Priority: Major

> {{ParametersInterceptor.isParameterAnnotatedAndAllowlist}} resolves the
> binding target once and uses it for both steps:
> Object target = parameterAuthorizer.resolveTarget(action);
> if (!parameterAuthorizer.isAuthorized(name, target, action)) {
> return false;
> }
> parameterAllowlister.primeAllowlistForPath(name, target);
> For a ModelDriven action, {{resolveTarget}} returns the model. Since WW-5698,
> {{isAuthorized}} may authorise a parameter against a member declared on the
> *action* rather than on the model — that is the whole point of scoping the
> exemption. The subsequent {{primeAllowlistForPath}} call still primes against
> the model, so for such a parameter the classes along the path are never added
> to the {{ThreadAllowlist}}.
> With {{struts.allowlist.enable=true}}, the effect is that a correctly
> {{@StrutsParameter}}-annotated nested property on a ModelDriven action's own
> class is authorised and then dropped by the allowlist. It fails closed, so
> this is a functional bug rather than a security issue, but it is confusing to
> diagnose: the annotation is present and correct, and nothing in the logs
> points at the allowlist.
> h3. Suggested fix
> Prime against the object the authorisation was actually granted on — either
> by having {{ParameterAuthorizer.isAuthorized}} report which object it
> authorised against, or by priming against both the model and the action on
> the ModelDriven path.
