CVE-2026-77648: CWE-918 Server-Side Request Forgery (SSRF) in OpenStack Glance
CVE-2026-77648 is a server-side request forgery (SSRF) vulnerability in OpenStack Glance versions 30.0.0, 31.0.0, and 32.0.0. The /v2/tasks API accepts import tasks that bypass import filtering options, allowing an admin user to fetch internal URLs within the Glance service network using HTTP or HTTPS. This API has been restricted to admins since the Xena release and is deprecated in recent versions.
AI Analysis
Technical Summary
In OpenStack Glance through version 32.0.0, the /v2/tasks API allows admin users to create import tasks with type=import that bypass import_filtering_opts. This enables server-side request forgery (SSRF) attacks where internal URLs within the Glance service network can be fetched if they use the http:// or https:// schemes. The API has been admin-only since the Xena release and is deprecated in several later releases. No official remediation or patch has been documented at this time.
Potential Impact
An attacker with administrative privileges on the OpenStack Glance service can exploit this SSRF vulnerability to make the service fetch internal URLs, potentially exposing internal network resources. The impact is limited to information disclosure (low confidentiality impact) and does not affect integrity or availability. The CVSS score is low (2.2) reflecting the requirement for high privileges and limited impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the OpenStack vendor advisory for current remediation guidance. Since the API is deprecated and restricted to admins, limiting administrative access and disabling deprecated APIs where possible can reduce exposure. Monitor vendor channels for official fixes or updates.
