CVE-2026-83543Network attack vector

Authenticated data disclosure via arbitrary URL fetching

Published Sep 5, 2026 · Updated Sep 6, 2026

SSRF in WPSoul Greenshift before 13.2.0 allows remote authenticated users to read arbitrary URL responses through the WordPress server. The get-csv-to-json REST endpoint accepts its url argument without host or scheme validation and fetches that address server-side. Contributor-level access is required, and returned content can disclose data from external or internal HTTP services reachable by the site.
