HIGHPre-NVD 8.48.4—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2% (7th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

uniget is a universal installer and updater for (container) tools. Prior to 0.27.6, the hooks edit command in cmd/uniget/hooks.go concatenates an unvalidated hook filename with the selected hooks directory, allowing parent-directory components to escape that directory. The resulting path is passed to the configured editor, which can access or modify files outside the hooks directory with the privileges of the uniget process account. This issue is fixed in version 0.27.6.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
