CVE-2023-25453Network attack vector

Unauthenticated browser script execution

Published Aug 30, 2023 · Updated Apr 28, 2026

Reflected XSS in Ian Sadovy WordPress Tables 1.3.9 and earlier allows remote attackers to execute script through a crafted request. Patchstack has not published the affected parameter, code locus, or missing output-encoding operation that reflects attacker-controlled input into a generated page. No authentication is required to prepare the input, but a visitor must open the resulting request; successful exploitation runs script in that visitor’s browser context.
