    🚨 CRITICAL - Incus image download arbitrary file write via crafted Incus-Image-Hash header (CVE-2026-48769) Incus is vulnerable to an arbitrary file write in the http://github.com/lxc/incus/v7/cmd/incusd image download path when handling the Incus-Image-Hash header from remote image servers. The root cause is improper input validation leading to path traversal, allowing a crafted “hash” value to influence filesystem paths before integrity checks complete. An attacker exploits this by operating or tampering with an image server (or MITM’ing image traffic) so Incus pulls an image and processes the malicious header, requiring only that the host is configured to download from the attacker-controlled source. Impact is severe: files can be written outside the intended image directory prior to SHA-256 verification, enabling root-level command execution on the host (e.g., by dropping a cron job). 👉 Affected: http://github.com/lxc/incus/v7/cmd/incusd (versions affected not specified) | No fix yet - treat as suspicious

    Post summary

    CVE-2026-48769 exposes an arbitrary file write via crafted Incus-Image-Hash headers, enabling path traversal and root-level command execution; there is currently no patch or active exploitation reported.
