GHSA-p9wq-mjh8-q72m · Severity: high · Ecosystem: pip — OpenStack keystonemiddleware and python-keystoneclient vulnerable to man-in-the-middle attacks
The s3_token middleware in OpenStack keystonemiddleware before 1.6.0 and python-keystoneclient before 1.4.0 disables certification verification when the "insecure" option is set in a paste configuration (paste.ini) file regardless of the value, which allows remote attackers to conduct man-in-the-middle attacks via a crafted certificate, a different vulnerability than CVE-2014-7144.
Conclusion & alert: CVE-2015-1852 is rated Moderate Risk (48.6/100): CVSS Medium severity, with medium exploitation likelihood (EPSS 2.59%). Core evidence: EPSS rose +2.29% over the last day, indicating growing attacker interest. Mandatory action: Review affected assets and schedule remediation.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
EPSS lead: Daily EPSS estimates relative likelihood of exploitation; percentile ranks this CVE among scored vulnerabilities (higher = more severe relative rank).
