CVE-2026-1727 is a critical vulnerability in Google Cloud Gemini Enterprise (formerly Agentspace), published on 6 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

The Agentspace service was affected by a vulnerability that exposed sensitive information due to the use of predictable Google Cloud Storage bucket names.
