CVE-2026-111433 · Severity: high · CVSS 8.6 · Published 2026-11-12

openEuler iSulad is a container runtime that manages Linux containers. A symlink-following vulnerability in mount handling allows an attacker to craft a malicious container image that, when run, causes the iSulad daemon to copy sensitive host directories into the container's volume, exposing host data to the container process.

Technologies: [openEuler iSulad](https://junglewise.ai/threats/technologies/isulad). Vendors: [openEuler](https://junglewise.ai/threats/vendors/openeuler).

## Technical details

This is a UNIX symlink-following vulnerability in src/daemon/modules/spec/specs_mount.c that affects container initialization. An attacker can craft a malicious container image that exploits improper symlink handling during volume mount operations; when the platform or victim runs this image, the iSulad daemon copies sensitive host directories into an anonymous volume readable by the container, leading to host information disclosure.
