PolinRider malware fork of keycloak/keycloak (36859 stars) staging upstream injection using a previously-undocumented marker variant (global.i="A#-" instead of the known global['!']/global['_V']/globalThis.i= markers). A build/lint config file in the fork contains the payload (exact path not individually re-confirmed this pass; bucket-level content verification confirmed genuine). === UPSTREAM INJECTION ATTEMPT === Attack type: Fork-and-PR upstream injection Fork repo: Bragadeesh16/keycloak Parent repo: keycloak/keycloak (36859 stars) Fork created: 2026-02-26T15:57:18Z === PAYLOAD === Infected file: build/lint config file (exact path not re-confirmed this pass) Signature: new variant marker global.i="A#-..."
