CVE-2026-75915
CodeWhale versions before 0.8.64 contain an environment variable exposure vulnerability in the js_execution tool that fails to scrub parent process environment variables before spawning Node.js.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.62%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
