CVE-2026-115376: Incus 7.0.1 before 7.0.2 and 7.2.0 before 7.5.0 Project Restriction Bypass via Custom Volume Copy

HighCVSS 8.3 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 33/100)

  • 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: 0.27% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: lxc incus 7.0.2, 7.5.0.

Low priority for now. Upgrade to lxc incus 7.0.2, 7.5.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Incus 7.0.1 before 7.0.2 and 7.2.0 before 7.5.0 contains an authorization bypass vulnerability that allows project-restricted clients to copy volumes by omitting source.type. Attackers can send crafted POST requests to the custom volumes endpoint with a chosen source.project to copy and read other projects' volumes, snapshots, and configuration.
