CVE-2025-0554Network attack vector

Stored XSS via unescaped Feed Name

Published Jan 18, 2025 · Updated Apr 8, 2026

Stored cross-site scripting in Podlove Podcast Publisher 4.1.25 and earlier allows remote authenticated users to execute scripts via a Feed Name. The Feed Name setting accepts unsanitized input and later renders it without context-appropriate output escaping, preserving attacker-supplied script markup. Administrator-level access is required, and exposure is limited to multisite installations or sites where unfiltered_html is disabled; viewing an affected page executes the stored script in that user's browser.
