CVE-2026-44916: CWE-1336 Improper Neutralization of Special Elements Used in a Template Engine in OpenStack Ironic
CVE-2026-44916 is a low-severity vulnerability in OpenStack Ironic up to version 35. x where the instance_info['ks_template'] is rendered without sandboxing. This improper neutralization of special elements in the template engine could potentially allow certain unintended behaviors. The vulnerability has a CVSS score of 3. 0, indicating low impact, with network attack vector, high attack complexity, and requiring high privileges but no user interaction. There is no known exploit in the wild and no official patch or remediation guidance has been provided yet.
AI Analysis
Technical Summary
OpenStack Ironic versions through 35.x contain a vulnerability identified as CVE-2026-44916 (CWE-1336) where the 'ks_template' field within instance_info is rendered without sandboxing. This improper neutralization of special elements in the template engine could lead to limited impact scenarios. The CVSS 3.1 vector is AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:N/A:N, indicating a network attack vector, high attack complexity, requiring high privileges, no user interaction, with a scope change and low confidentiality impact only.
Potential Impact
The vulnerability allows for improper neutralization of special elements in the template engine, potentially leading to limited confidentiality impact. There is no indication of integrity or availability impact. Exploitation requires high privileges and has high attack complexity, reducing the likelihood of exploitation. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or temporary mitigation is currently documented, users should monitor OpenStack Ironic vendor advisories for updates. Until a patch is available, restrict access to high-privilege users and consider limiting exposure of the affected template rendering functionality.
