SCA: security update for elysia (GHSA-8vch-m3f4-q8jf)
high Tenable Cloud Security Plugin ID 436308
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Elysia is a Typescript framework for request validation, type inference, OpenAPI documentation and client-
server communication. Versions 1.4.17 and below are subject to arbitrary code execution from cookie
config. When dynamic cookies are enabled (e.g. there an existing cookie schema), the cookie config is
injected into the compiled route without first being sanitised. Availability of this exploit is generally
low, but when combined with GHSA-hxj9-33pp-j2cc, it allows for a full RCE chain. An attack requires write
access to either the Elysia app's source code (in which case the vulnerability is meaningless) or write
access to the cookie config (perhaps where it is assumed to be provisioned by the environment). This issue
is fixed in version 1.4.18. (CVE-2025-66457)
