Deux vulnérabilités ont été découvertes dans neon :
- un déni service est possible, via des fichiers au format XML ou un serveur DAV malveillant, si la bibliothèque expat est utilisée (CVE-2009-2473) ;
- le mécanisme de vérification des certificats utilisés lors de sessions SSL peut être contourné, ce qui permet des attaques de type homme-au-milieu (CVE-2009-2474).
