The EPSS score is below 1\u202f%, indicating a low current likelihood of exploitation. The likely attack vector is via the file import interface, which may be exposed over the network; this is inferred from the fact that the file import process is mentioned as the mechanism for the overwrite. The issue is not listed in the CISA KEV catalog. Successful exploitation would allow an attacker to gain code execution or disclose information."}}}}, "created": "2026-03-31T19:56:47.925934+00:00", "title": "Arbitrary File Overwrite in Funambol Zefiro Leads to Remote Code Execution", "updated": "2026-04-07T08:08:21.873287+00:00", "vendors": ["funambol", "funambol$PRODUCT$zefiro_cloud"]}
