### Note
GitHub incorrectly stated this vulnerability is identical to CVE-2025-69970, which describes the fact that authentication is disabled by default. This advisory describes an exploit chain that enables authentication bypass via the heartbeat refresh endpoint when authentication is enabled. This misleads users into thinking that enabling authentication would mitigate this vulnerability. Please see the patch for more information: https://github.com/frangoteam/FUXA/commit/fe82348d160904d0013b9a3e267d50158f5c7afb.
### Description
An authentication bypass vulnerability in FUXA allows an unauthenticated, remote attacker to gain administrative access via the heartbeat refresh API and execute arbitrary code on the server. Th

CVE-2026-96951 [HIGH] Patch Tuesday - October 2026
Microsoft is publishing 1,413 own-product vulnerabilities on October 2026 Patch Tuesday , including 1,102 vulnerabilities in Windows. Anyone who enjoyed last month’s record-setting Patch Tuesday will love the October 2026 edition, because it’s much bigger still. As Rapid7 has noted over the course of 2026, there is every reason to suppose that vulnerability volumes will continue to rise. Microsoft is aware of exploitation in the wild for just one of the vulnerabilities published today, as well as public disclosure for two others.
