CVE-2026-66603Network attack vector

Contributor stored XSS

Published Aug 18, 2026 · Updated Aug 19, 2026

Stored XSS in David Artiss Draft List before 2.6.5 allows remote authenticated users to run script in a victim browser. Patchstack states that Contributor privileges and user interaction are required, but the public CNA, NVD, and vendor changelog do not disclose the input field, rendering sink, or code path that stores and later emits attacker-controlled content without neutralization. Reachability therefore depends on low-privilege WordPress access and a victim viewing affected plugin output, and the public record does not substantiate impact beyond script execution in the site origin.
