CVE-2026-57809Network attack vector

Browser script execution via undisclosed reflected input

Published Jul 23, 2026 · Updated Jul 23, 2026

Reflected cross-site scripting in AffiliateWP 2.34.0 and earlier allows remote attackers to run script in a victim's browser. Patchstack has not disclosed the affected request parameter, output sink, or code locus; it reports only unauthenticated reflected XSS. Exploitation requires a user to follow a crafted link or take a comparable action, after which the payload runs in the affected site's origin and can read or alter browser-accessible data.
