High (7.3) in docker docker sandboxes. EPSS 0.1% estimated probability of exploitation activity in the next 30 days.
On this page
Docker Sandboxes reuses existing state and configuration directories without verifying their ownership. If sbx or sandboxd is run as root with HOME or, on Linux, XDG_STATE_HOME pointing to an attacker-controlled location, a local unprivileged user can substitute control-plane sockets and configuration trusted by the root process, potentially executing commands as root. Exploitation requires a privileged invocation with an attacker-influenced environment. The issue affects Linux and macOS and is fixed in version 0.53.0.

Explain CVE-2026-126329 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-126329?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-126329?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-126329 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
