+# bug-1958: apiserver lets any rbac:control grant create roles and extend its own role (privilege escalation)
+
+## Description
+**Observed:** (source reading; follow-up of the 2026-10-10 P0 fixes (bug-1936..1957))
+Reported by the bug-1952 fix: role create/update in `controllers/roles.go` accepts any `rbac:control` scope, so a user holding `rbac:control` with scope `self` can add `cluster:control` (or any permission) to a role it already holds: the same escalation bug-1952 closed for user-role assignment, by another route.
+
+**Expected:** Creating roles or changing a role's permissions requires `rbac:control` with scope `all` (as user-role changes do since bug-1952).
+**Impact:** Security: privilege escalation through role editing.
+**Found by:** follow-up of the 2026-10-10 P0 fixes (bug-1936..1957)
+## Environment
+- OS: no /etc/os-release; Docker container; NixOS kernel; kernel Linux 6.18.33 x86_64
+- libc: glibc 2.42-47 (interpreter /nix/store/wb6rhpznjfczwlwx23zmdrrw74bayxw4-glibc-2.42-47/lib/ld-linux-x86-64.so.2)
+- Toolchain: gcc (GCC) 15.2.0, meson 1.9.1
+- Build: asan (xce.build)
+- Code: scheduler-framework @ 19be145d-dirty
+- Deployment: any (found by source reading; confirmed by the RED test of the fix)
+
+## Reproduction
+1. Give user mallory a role with `rbac:control` scoped `self`.
+2. As mallory, add `cluster:control` (domain all) to that role through the roles API; it is accepted.
+- Frequency: deterministic (by code reading; confirmed by the RED test of the fix)
+- Evidence: the code sites quoted in Description; no logs kept.
