CVE-2026-46689
CVE-2026-46689 updated by NVD
Summary
Kanidm is an identity management platform. Prior to version 1.9.3, a single unauthenticated GET to any /scim/v1/... endpoint with a ?filter= query string of a few thousand nested parentheses (≈ 4–12 KB) drives the recursive-descent PEG parser past the worker thread's stack guard page. Rust responds to stack overflow with std::process::abort() — the entire kanidmd process exits. The parse runs inside axum's Query extractor, before any handler body and therefore before any ACL check. This issue has been patched in version 1.9.3.
