CVE-2026-39416
Stored XSS in modal item preview for long item content in AIL Framework
Description
AIL framework is an open-source platform to collect, crawl, process and analyse unstructured data. Prior to 6.8, a stored cross-site scripting (XSS) vulnerability was identified in the modal item preview functionality. When item content longer than 800 characters was processed, attacker-controlled content was returned without an explicit text/plain content type, allowing the browser to interpret the response as active HTML. This could result in execution of arbitrary JavaScript in the context of an authenticated user viewing a crafted item. This vulnerability is fixed in 6.8.

Action Type Old Value New Value Added Translation Title: ail-framework de ail-project, Description: El framework AIL es una plataforma de código abierto para recopilar, rastrear, procesar y analizar datos no estructurados. Antes de la versión 6.8, se identificó una vulnerabilidad de cross-site scripting (XSS) almacenado en la funcionalidad de vista previa de elementos modales. Cuando se procesaba contenido de un elemento de más de 800 caracteres, se devolvía contenido controlado por el atacante sin un tipo de contenido text/plain explícito, lo que permitía que el navegador interpretara la respuesta como HTML activo. Esto podría resultar en la ejecución de JavaScript arbitrario en el contexto de un usuario autenticado que visualizara un elemento manipulado. Esta vulnerabilidad está corregida en la versión 6.8. -
