CVE-2026-63647

CordysCRM SSE Notification Stream Hijack via `/sse/subscribe` PUBLISHED

Description (CNA)

CordysCRM is an open source AI-powered customer relationship management system that supports private deployment. Prior to 1.7.2, SseController exposes the anonymous /sse/subscribe, /sse/broadcast, and /sse/close endpoints because ShiroFilter.addPublicPathFilters permits the SSE paths, and the endpoints trust the caller-controlled userId instead of deriving an identity from an authenticated principal. An unauthenticated caller can use /sse/subscribe to read another user's workflow events, approval requests, mentions, and alerts, use /sse/broadcast to inject SYSTEM_HEARTBEAT messages into another user's stream, or use /sse/close to terminate another user's channel. This vulnerability is fixed in 1.7.2.
