Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Tandoor Recipes, an application for managing recipes, planning meals, and building shopping lists, contains a Jinja2 server-side template injection vulnerability tracked as CVE-2025-23211. The flaw, assigned CWE-1336 and CWE-94, permits arbitrary command execution and carries a CVSS 3.1 score of 9.9. It is present in versions prior to the 1.5.24 release.

Any authenticated user can exploit the issue over the network to run commands on the underlying server. When the application is deployed via the provided Docker Compose configuration, the commands execute with root privileges, resulting in full host compromise including confidentiality, integrity, and availability impacts.

The project security advisory and associated commit indicate that the vulnerability is resolved in version 1.5.24. The fix is documented in the template_helper.py file and the corresponding GitHub advisory GHSA-r6rj-h75w-vj8v.

The EPSS score currently stands at 0.6314 with a recorded peak of 0.6840, reflecting sustained exploitation interest following disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static analysis can discover missing neutralization of template directives.

Input validation rejects or sanitizes untrusted data before it reaches the template engine, stopping injection of special syntax.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

Security engineering principles require use of safe templating APIs and proper escaping of external input.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper input neutralization in template engines to prevent injection.

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

finds

Security testing can detect template-injection flaws but does not itself implement neutralization controls.

prevents

Secure development life cycle mandates input validation and sanitization that directly prevents template-injection weaknesses.

prevents

Application security requirements explicitly call for neutralizing special elements in template engines.

prevents

Secure architecture principles reduce the likelihood of unsafe template processing but do not prescribe specific neutralization techniques.

prevents

Secure coding standards require proper escaping or sandboxing of template directives, directly mitigating CWE-1336.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
