CVE-2025-14375Network attack vector

Reflected XSS via unsanitized className parameter

Published Jan 16, 2026 · Updated Jan 16, 2026

Reflected XSS in RebelCode WP RSS Aggregator 5.0.10 and earlier allows remote attackers to run scripts through the className parameter. Renderer::parseArgs copies the className value into the display HTML class after trimming it, without restricting it to a valid HTML class. Exploitation requires a user to open an attacker-crafted link, after which the injected script runs in that user’s browser under the affected site’s origin.
