CVE-2025-7842Network attack vector

RSS feed deletion via missing nonce validation

Published Aug 23, 2025 · Updated Apr 8, 2026

Cross-site request forgery in Silencesoft RSS Reader 0.6 and earlier allows remote attackers to delete RSS feeds via forged requests. The sil_rss_edit_page administration page fails to validate a request nonce correctly, so a browser can submit an RSS feed deletion under the administrator's active session. Exploitation requires an unauthenticated attacker to induce a site administrator to act on crafted content, and the documented consequence is RSS feed deletion.
