PYSEC-2026-2409

Vulnerability from pysec - Published: 2026-07-13 15:15 - Updated: 2026-07-13 16:03

Details

Summary

The published ghcr.io/jo-jo98/ciguard container image inherits the default root user because the Dockerfile lacks a USER directive. ciguard is a static analyser with no need for root privileges; running as root inside a container makes any future container-runtime escape CVE more impactful than it needs to be.

Threat scenario

Defence-in-depth gap. Without a known container-runtime CVE in the chain, this finding is not directly exploitable. Recent runc CVEs (e.g. CVE-2024-21626) provided escape primitives that depended on host UID = container UID = 0 for full impact; with this fix, any future such escape primitive lands as a non-root user on the host.

Patch

Dockerfile adds RUN groupadd -r ciguard && useradd -r -g ciguard -d /home/ciguard -m -s /usr/sbin/nologin ciguard && chown -R ciguard:ciguard /reports /policies-mount /app.
Followed by USER ciguard before the CMD directive.
Trivy DS-0002 misconfig clears (Tests: 20 SUCCESSES: 20 FAILURES: 0).

Discovery

Found by Trivy filesystem scan during ciguard's first self-conducted pentest cycle, 2026-04-26.

CVSS Scoring

CVSS v3.1: CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:N — 2.0 (Low)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
