CVE-2025-58146

There are multiple issues. 1. Updates to the XAPI database sanitise input strings, but try generating the notification using the unsanitised input. This causes the database's event thread to terminate and cease further processing. 2. XAPI's UTF-8 encoder implements v3.0 of the Unicode spec, but XAPI uses libraries which conform to the stricter v3.1 of the Unicode spec. This causes some strings to be accepted as valid UTF-8 by XAPI, but rejected by other libraries in use. Notably, such strings can be entered into the database, after which the database can no longer be loaded. 3. There is no input sanitisation for Map/Set updates on objects in the XAPI database.

Summary		(es) Hay múltiples problemas. 1. Las actualizaciones a la base de datos XAPI sanitizan las cadenas de entrada, pero intentan generar la notificación usando la entrada no sanitizada. Esto provoca que el hilo de eventos de la base de datos termine y cese el procesamiento posterior. 2. El codificador UTF-8 de XAPI implementa la v3.0 de la especificación Unicode, pero XAPI utiliza bibliotecas que cumplen con la v3.1 más estricta de la especificación Unicode. Esto provoca que algunas cadenas sean aceptadas como UTF-8 válido por XAPI, pero rechazadas por otras bibliotecas en uso. En particular, dichas cadenas pueden introducirse en la base de datos, después de lo cual la base de datos ya no puede cargarse. 3. No hay sanitización de entrada para actualizaciones de Map/Set en objetos en la base de datos XAPI.
