Published Updated By the CyberSecBulletin desk

CVE-2026-79695 is a high-severity improper handling of highly compressed data (data amplification) vulnerability in Secure Connect Gateway 5.0 - Application from Dell, with a CVSS 3.1 base score of 7.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 5.36.00.00 or later as the first without the flaw, so updating Secure Connect Gateway 5.0 - Application to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.33% chance of exploitation within 30 days, which is low compared with other CVEs.
