Script execution via reflected Subscribe Button input
Published Aug 20, 2026 · Updated Aug 20, 2026
Cross-site scripting in Podlove Podcast Publisher before 4.5.5 allows remote attackers to execute arbitrary script via crafted Subscribe Button input. Podlove states that the flaw was in the locally delivered Subscribe Button, but public records do not identify the exact parameter or rendering path that reflected attacker-controlled data back into page content. Exploitation requires a victim to load a crafted request or page that renders the local button code, so the practical impact is script execution in the visiting browser rather than direct server compromise.
