CVE-2024-6398Network attack vector

Block-page data disclosure via same-origin bypass

Published Jul 15, 2024 · Updated Aug 1, 2024

Information disclosure in Skyhigh Secure Web Gateway 11.x before 11.2.24 and 12.x before 12.2.10 allows remote attackers to read block-page data. The block-page redirect flow permits a third-party origin to read content generated for a blocked request, bypassing browser same-origin isolation. Exploitation requires browser interaction through the gateway; only data placed in customized block pages is exposed, and recommended URL-risk policies reduce reachability.
