Descriptions

HedgeDoc is an open-source, web-based, self-hosted, collaborative markdown editor. Images uploaded with HedgeDoc version 1.9.1 and later have an enumerable filename after the upload, resulting in potential information leakage of uploaded documents. This is especially relevant for private notes and affects all upload backends, except Lutim and imgur. This issue is patched in version 1.9.3 by replacing the filename generation with UUIDv4. If you cannot upgrade to HedgeDoc 1.9.3, it is possible to block POST requests to `/uploadimage`, which will disable future uploads.

HedgeDoc es un editor de código abierto, basado en la web, auto-alojado y colaborativo. Las imágenes subidas con HedgeDoc versiones 1.9.1 y posteriores, presentan un nombre de archivo enumerable después de la subida, resultando en un potencial filtrado de información de los documentos subidos. Esto es especialmente relevante para las notas privadas y afecta a todos los backends de subida, excepto Lutim e imgur. Este problema ha sido corregido en versión 1.9.3, al sustituir la generación de nombres de archivo por UUIDv4. Si no puedes actualizar a HedgeDoc versión 1.9.3, es posible bloquear las peticiones POST a "/uploadimage", lo que deshabilitará futuras subidas
