The `namespace` argument arrives unvalidated from the CEL expression `generator.apply(\"\", [...])`.\n\n### Version-Specific Impact\n\n**v1.18.0, v1.18.1 (affected via NamespacedMutatingPolicy only):**\n\nThe nmpol CEL compiler unintentionally exposes the `generator` library to match condition expressions. A namespaced mutating policy can invoke `generator.apply()` in a boolean CEL expression such as `matchConditions`, triggering the admission controller to generate resources in any namespace at request time. This side effect executes with the admission controller's cluster-wide privileges.\n\nNamespacedGeneratingPolicy is **not** a vector in v1.18.1 due to incomplete webhook and background processing wiring (not registered or functional).\n\n### Root Cause\n\nThe admission valida","public_affected_ranges":[">= 1.18.0, <= 1.18.1"]}],"null_published_at":"2026-11-02T10:00:37.210Z","source_updated_at":"2026-08-26T14:21:54.000Z","source_disclosed_at":"2026-08-26T14:21:54.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-02T09:56:37.775Z"}],"next_cursor":null,"snapshot_revision":"42594"}
