Keycloak account takeover (CVE-2026-18963) via unauthenticated reset-credentials Required Action bypass, including realm and username enumeration, a takeover verdict, and an optional post-ATO token or admin shell. Use when assessing a Keycloak realm for the reset-credentials bypass or confirming whether an account can be taken over.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install
mdr add novaestellar/novahaku/keycloak-exploit@sha256:cadfe4933c644ebcThe line at the top of this page pins the label git:20260925.9330cc6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
