This vulnerability, known as Server-Side Template Injection, allows an attacker to execute unauthorized code. By manipulating specific input fields, a malicious tenant can inject harmful commands into templates that are processed twice. This bypasses security measures, enabling the attacker to run arbitrary code within the `release-service-utils` system and potentially gain access to sensitive credentials."], "mitigation": {"lang": "en:us", "value": "Suggestion: Remove the second-pass render, or if double expansion is required use jinja2.sandbox.ImmutableSandboxedEnvironment for both passes and reject/escape '{{', '{%', '{#' sequences in template_data values before rendering. Add a unit test asserting that a data value containing Jinja syntax is emitted literally."}, "name": "CVE-2026-92218", "public_date": "2026-09-16T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2026-92218\nhttps://nvd.nist.gov/vuln/detail/CVE-2026-92218"], "statement": "The vulnerability in `release-service-utils` is rated as Important because a malicious tenant can achieve arbitrary code execution. This server-side template injection flaw arises from a two-pass rendering process where user-controlled input is re-evaluated as live Jinja template syntax, bypassing intended sandboxing. Exploitation requires the ability to influence specific text fields within release inputs, leading to compromise of the `release-service-utils` pod and potential access to sensitive credentials.", "threat_severity": "Important"}
