19
FAUCET Score

CVE-2016-7031 describes a vulnerability in Ceph's RGW code (versions prior to 10.0.1) where an authenticated-read ACL on a bucket can be bypassed, allowing remote attackers to list bucket contents via a crafted URL. This high-severity vulnerability (CVSS 7.5) requires no authentication or user interaction and could lead to significant information disclosure. While no public exploit intelligence or active exploitation has been observed, and community discussion is minimal, organizations using affected Ceph versions should prioritize patching to mitigate this risk.
