  3. CVE-2026-29038
changedetection.io is a free open source web page change detection tool. Prior to version 0.54.4, there is a reflected cross-site scripting (XSS) vulnerability identified in the /rss/tag/ endpoint of changedetection.io. The tag_uuid path parameter is reflected directly in the HTTP response body without HTML escaping. Since Flask returns text/html by default for plain string responses, the browser parses and executes injected JavaScript. This issue has been patched in version 0.54.4.

Summary
  • (es) changedetection.io es una herramienta gratuita de código abierto para la detección de cambios en páginas web. Antes de la versión 0.54.4, existe una vulnerabilidad de cross-site scripting (XSS) reflejado identificada en el endpoint /rss/tag/ de changedetection.io. El parámetro de ruta tag_uuid se refleja directamente en el cuerpo de la respuesta HTTP sin escape HTML. Dado que Flask devuelve text/html por defecto para respuestas de cadena de texto plano, el navegador analiza y ejecuta JavaScript inyectado. Este problema ha sido parcheado en la versión 0.54.4.
