CVE-2026-86335: LXD Cross-Project Private Image Theft via Unsanitized GetImageFromAnyProject Local Reuse
Noroxi assessment
Priority: Monitor (action score 25/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
- Fixed version: Canonical LXD 5.0.10, 5.21.8, 6.10.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to Canonical LXD 5.0.10, 5.21.8, 6.10 or later.
