MaxKB is an open-source AI assistant for enterprise. In version 2.10.3-lts and earlier, the model parameter form route authorizes the path workspace but ModelSerializer.ModelParams loads and saves a Model by id alone without including workspace_id in the query. An authenticated user with model read permission in an attacker-controlled workspace can supply a known victim model_id to read or overwrite the victim's model_params_form in another workspace, potentially altering workflows that use those defaults. No fixed version is available as of this review.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
