Mind the (Patch) Gap: Multiple Chinese Threat Actors Chain 0-day Exploits in Chrome & Windows (opens in a new tab)
Why readTwo separate Chinese threat actors are running the same Chrome zero-day chain, CVE-2026-85046, against NGO targets via a reflected XSS on a US university site.
Volexity detected spear-phishing on 1 September 2026 from UTA0560 that abused a reflected XSS flaw on a US university website to redirect victims into a multi-stage exploit chain built on Chrome zero-day CVE-2026-85046. Email telemetry showed JungleBamboo (APT31/Violet Typhoon/TA412) exploiting the identical chain against different targets, using separate infrastructure and different post-exploitation malware. The bug was reported to Chromium on 4 August 2026 and the fix landed in the open-source tree before shipping, leaving a patch-gap window that both actors worked.
