CVE-2026-59674

LPE from suricata user to root due to chown in %post in suricata packaging

Published Jul 14, 2026 CVSS 4.0 · 7.1 High EPSS < 1% KEV · Not listed

Description

A UNIX Symbolic Link (Symlink) Following vulnerability in openSUSE Tumbleweed suricata package allows the suricata user to escalate to root.

This issue affects openSUSE Tumbleweed: from ? before 8.0.5-2.1; openSUSE Tumbleweed: from ? before 8.0.5-2.1.

Analysis

Technical impact

The suricata package on openSUSE Tumbleweed contains a Unix symbolic link following flaw that is triggered during its post‑install script. The flaw permits an unprivileged suricata user to create or influence a malicious symlink pointing to a privileged file, thereby allowing the suricata process to inadvertently overwrite root‑owned files. The result is local privilege escalation to root, corresponding to CWE‑59 (Relative Path Traversal) and CWE‑61 (Improper Control of File or Directory Access Path).

Affected Systems

All openSUSE Tumbleweed releases with Suricata before version 8.0.5-2.1 are affected.

Risk and Exploitability

The CVSS score of 7.1 indicates high severity, whereas the EPSS score of below 1% suggests a very low probability of exploitation today. This vulnerability is not listed in the CISA KEV catalog. Exploitation requires local access that can influence the post‑install script or the creation of a crafted symbolic link, so the attack vector is local. Successful exploitation would give the attacker root privileges, affecting confidentiality, integrity, and availability of the host.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade Suricata to version 8.0.5-2.1 or later from the openSUSE Tumbleweed repository.
If upgrading is not possible, uninstall or disable the Suricata service to eliminate the vulnerable account.
Monitor system logs and file creation events for suspicious symbolic links that point to privileged files and correct them if discovered.
