Prior to version 7.2.0, the `record-output` parameter of the `/instances/$name/exec` endpoint stores the output of the command in the `exec-output` directory of the instance. If `exec-output` is a symlink, file named `exec_UUID.stdout` and `exec_UUID.stderr` can be written to an arbitrary location where the `.stdout` file will contain arbitrary content. This behavior can be abused for arbitrary command execution. Version 7.2.0 contains a patch.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-73"],"references":["https://github.com/lxc/incus/security/advisories/GHSA-73hr-m85f-64v9","https://github.com/lxc/incus/security/advisories/GHSA-73hr-m85f-64v9"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-48750","score":0.00731,"percentile":0.54008,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-73hr-m85f-64v9","url":"https://osv.dev/vulnerability/GHSA-73hr-m85f-64v9","summary":"Incus has an arbitrary file write on host via `exec-output` symlink in crafted image","modified":"2026-07-07T20:41:33.230582429Z","packages":[{"ecosystem":"Go","name":"github.com/lxc/incus/v7/cmd/incusd","purl":"pkg:golang/github.com/lxc/incus/v7/cmd/incusd","ranges":["<7.2.0"],"fixed":["7.2.0"]}]},{"id":"GO-2026-5801","url":"https://osv.dev/vulnerability/GO-2026-5801","summary":"Incus has an arbitrary file write on host via `exec-output` symlink in crafted image in github.com/lxc/incus","modified":"2026-07-07T20:30:15.121692731Z","packages":[{"ecosystem":"Go","name":"github.com/lxc/incus","purl":"pkg:golang/github.com/lxc/incus","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/lxc/incus/v6","purl":"pkg:golang/github.com/lxc/incus/v6","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/lxc/incus/v7","purl":"pkg:golang/github.com/lxc/incus/v7","ranges":["<7.2.0"],"fixed":["7.2.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
