CVE-2026-77648: CWE-918 Server-Side Request Forgery (SSRF) in OpenStack Glance
Description
CVE-2026-77648 is a server-side request forgery (SSRF) vulnerability in OpenStack Glance through version 32.0.0. The issue exists in the /v2/tasks API when handling type=import tasks, which bypasses import_filtering_opts and allows an admin user to fetch internal URLs within the Glance service network using HTTP or HTTPS. This API has been restricted to admin users since the Xena release and has been deprecated for several releases. The vulnerability has a low CVSS score of 2.2 and does not affect confidentiality, integrity, or availability beyond limited information disclosure.

Technical Analysis
OpenStack Glance versions up to 32.0.0 have an SSRF vulnerability in the /v2/tasks API for import tasks. This flaw allows authenticated admin users to bypass import filtering options and access internal URLs via HTTP or HTTPS protocols. The API endpoint involved has been admin-only since the Xena release and is deprecated. The CVSS 3.1 base score is 2.2, reflecting low impact with high attack complexity and required privileges. No known exploits are reported in the wild.
Potential Impact
An authenticated administrator can use the /v2/tasks API to perform SSRF attacks by fetching internal URLs within the Glance service network. The impact is limited to low confidentiality loss as per the CVSS score, with no integrity or availability impact. Since the API is admin-restricted and deprecated, the risk is further reduced.
Mitigation Recommendations
No explicit patch or remediation details are provided in the input data. 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 admin access and monitoring usage of the /v2/tasks API can reduce risk until a fix is applied.
