CVE-2026-27977

A CSRF check bypass flaw has been discovered in Next.js. In the next dev, cross-site protection for internal websocket endpoints could treat Origin: null as a bypass case even if allowedDevOrigins is configured, allowing privacy-sensitive/opaque contexts for example sandboxed documents to connect...

CVE-2026-27978

A CSRF check bypass flaw has been discovered in Next.js. The origin: null was treated as a "missing" origin during Server Action CSRF validation. As a result, requests from opaque contexts such as sandboxed iframes could bypass origin verification instead of being validated as cross-origin...

Origin Validation Error

Overview Glances is an A cross-platform curses-based monitoring tool Affected versions of this package are vulnerable to Origin Validation Error in the REST/WebUI FastAPI application due to the lack of host header validation and the absence of an allowlist for trusted hosts. An attacker can gain...
