{"apiVersion":"1.0","identifier":"CVE-2026-63297","description":"An authorization bypass vulnerability in LXD due to a timing flaw during configuration merging allows an authenticated attacker to bypass target project restrictions during cross-project instance copies. When copying an instance to a target project, LXD performs restriction checks before configuration merging is complete, creating a time-of-check to time-of-use (TOCTOU) condition. An attacker can exploit this flaw to copy instances with disallowed high-privilege configurations into restricted projects, bypassing security controls.","publishedAt":"2026-08-12T20:17:47","lastModifiedAt":"2026-08-28T15:24:38","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-63297","cvssScore":9.9,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.00196,"riskScore":1.01,"affectedProduct":"LXD","affectedVersions":"unknown","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-63297","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-63297","en":"https://www.redsauce.net/en/cves/CVE-2026-63297","fr":"https://www.redsauce.net/fr/cves/CVE-2026-63297","pt":"https://www.redsauce.net/pt/cves/CVE-2026-63297","de":"https://www.redsauce.net/de/cves/CVE-2026-63297","sk":"https://www.redsauce.net/sk/cves/CVE-2026-63297","el":"https://www.redsauce.net/el/cves/CVE-2026-63297"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-63297"}}
