CVE-2026-44220: ciguard: discover_pipeline_files follows symlinks out of scan root

LowCVSS 3.2 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 12/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.21% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
Fixed version: Jo-Jo98 ciguard 0.8.2.

Low priority for now. Upgrade to Jo-Jo98 ciguard 0.8.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

ciguard is a static security auditor for CI/CD pipelines. From 0.8.0 to 0.8.1 , the discover_pipeline_files() function in src/ciguard/discovery.py walks a directory tree following symlinks, with cycle protection via tracking visited resolved paths. An attacker who can plant a symlink in a directory the user (or AI agent) scans can cause discovery to walk into the symlink target and return paths to pipeline-shaped files outside the requested root. This vulnerability is fixed in 0.8.2.
