What is CVE-2026-44218?

CVE-2026-44218 is a low-severity improper privilege management vulnerability in ciguard (pip), affecting versions >= 0.1.0, <= 0.8.1. It is fixed in 0.8.2. The application assigns, modifies, tracks, or checks privileges incorrectly, allowing a user to gain elevated access.

How severe is CVE-2026-44218?

CVE-2026-44218 has a CVSS score of 3.0 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

Which versions of ciguard are affected by CVE-2026-44218?

ciguard (pip) versions >= 0.1.0, <= 0.8.1 is affected.

Is there a fix for CVE-2026-44218?

Yes. CVE-2026-44218 is fixed in 0.8.2. Upgrade to this version or later.

Is CVE-2026-44218 exploitable, and should I be worried?

Whether CVE-2026-44218 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2026-44218 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

How do I fix CVE-2026-44218?

Upgrade ciguard to 0.8.2 or later.

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.

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)
CVSS v4.0: CVSS:4.0/AV:L/AC:H/AT:P/PR:H/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N, 3.4 (Low) per Cycle 1 report; GitHub's calc 1.8 (Low). Both Low.

Verification

$ docker run --rm ghcr.io/jo-jo98/ciguard:v0.8.2 id
uid=999(ciguard) gid=999(ciguard) groups=999(ciguard)

Impact

The application assigns, modifies, tracks, or checks privileges incorrectly, allowing a user to gain elevated access. Typical impact: privilege escalation beyond the intended level.

CVE-2026-44218 has a CVSS score of 3.0 (Low). The vector is requires local access, high privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (0.8.2); upgrading removes the vulnerable code path.

Affected versions

ciguard (>= 0.1.0, <= 0.8.1)

Security releases

ciguard → 0.8.2 (pip)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Remediation advice

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).
