{"apiVersion":"1.0","identifier":"CVE-2026-61897","description":"An Ubuntu-specific patch to AccountsService before 23.13.9-8ubuntu7 only partially drops privileges before launching language helper scripts. It changes the effective UID/GID to the target user but leaves the real UID as 0 (root). A shell spawned by a helper script inherits ruid=0 and may reset its effective UID to root, enabling local privilege escalation.","publishedAt":"2026-08-20T15:17:38","lastModifiedAt":"2026-08-28T15:24:38","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-61897","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00097,"riskScore":0.79,"affectedProduct":"AccountsService","affectedVersions":"cannotmatch","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-61897","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-61897","en":"https://www.redsauce.net/en/cves/CVE-2026-61897","fr":"https://www.redsauce.net/fr/cves/CVE-2026-61897","pt":"https://www.redsauce.net/pt/cves/CVE-2026-61897","de":"https://www.redsauce.net/de/cves/CVE-2026-61897","sk":"https://www.redsauce.net/sk/cves/CVE-2026-61897","el":"https://www.redsauce.net/el/cves/CVE-2026-61897"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-61897"}}
