CVE-2026-15100: PostX searchnoresult attribute permits contributor stored XSS
PostX through 5.0.32 stores a contributor-controlled searchnoresult Advanced Search block attribute and later inserts it into data-noresultext without attribute-context escaping. wp_kses() alone does not make the value safe for that attribute, so script can run for visitors or an Editor/Administrator previewing the contributor's draft or pending post.
