Prior to versions 7.0.16 and 8.0.5, a malicious rule could potentially overwrite any file on the file system on rule load or reload. Versions 7.0.16 and 8.0.5 fix the issue. Some workarounds are available. Preprocess `load`+ `save` rules to disallow absolute filenames for save, use Suricata's privilege dropping to limit writable files, and/or configure landlock in suricata.yaml.\n\n## Affected\n\n- `suricata >= 7.0.0, < 7.0.16`\n- `suricata >= 8.0.0, < 8.0.5`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `suricata 8.0.5`\n\n## Vendor advisories\n\n- **Red Hat VEX** · updated 2026-09-16 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-45767.json)","depth":"sunlit","depthScore":24,"depthScoreParts":{"impact":24.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
