Unauthenticated stored XSS via unchecked debug imports

Published Mar 24, 2019 · Updated Oct 21, 2025

Stored XSS in Social Warfare before 3.5.3 allows remote attackers to execute browser scripts via debug-option imports. The load_options debug handler accepts an attacker-controlled swp_url and stores malicious option values that are rendered in social share links; Social Warfare Pro is also affected. Injection requires no credentials, while script execution requires a visitor to load an affected page and enables redirects to malicious sites.
