Flextype v1.0.0-alpha.3 Stored Arbitrary Expression Injection in ExpressionsDirective Allows Arbitrary File Read

Flextype CMS v1.0.0-alpha.3 stores unsanitized expressions in entries, letting privileged authenticated users achieve arbitrary file read when fields are parsed.

Flextype CMS v1.0.0-alpha.3 contains a stored arbitrary expression injection flaw in the Entries ExpressionsDirective. An authenticated user with privileges to create or modify entries can persist arbitrary expression syntax in an entry field. When the field is later retrieved or processed, the stored value is passed to parsers()->expressions()->parse(), leading to arbitrary file read on the server.

CVE-2026-82426 (rated important) affects Apache Storm Nimbus (org.apache.storm:storm-server) versions 3.0.0 before 3.1.0. Nimbus accepted the uploadedJarLocation argument of submitTopology/submitTopologyWithOpts as a server-side path and opened it directly, without verifying the caller had actually uploaded that file via beginFileUpload. This enables arbitrary file read on the Nimbus host; the issue is fixed in version 3.1.0.
