Vulnerability from certfr_avis
De multiples vulnérabilités ont été découvertes dans Roundcube. Certaines d'entre elles permettent à un attaquant de provoquer un déni de service à distance, une falsification de requêtes côté serveur (SSRF) et une injection de code indirecte à distance (XSS).
Solutions
Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).
