Published Oct 16, 2023 · Updated Apr 28, 2026

Cross-site request forgery in SendPulse Free Web Push 1.3.1 and earlier allows remote attackers to change plugin settings. The sendpulse_config function accepts configuration requests without requiring a valid WordPress nonce. Exploitation requires an authenticated site administrator to follow a malicious link or visit a crafted page, and the resulting write is limited to the plugin configuration.
