The value is interpolated unescaped into a GNU sed replacement expression, allowing an attacker to inject a sed -e- flag and arbitrary shell commands that execute with the privileges of the AccountsService helper process (real UID 0) via the SetLanguage D-Bus method.","publishedAt":"2026-08-20T15:17:38","lastModifiedAt":"2026-08-28T15:24:38","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-61898","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.0013,"riskScore":0.79,"affectedProduct":"accountsservice","affectedVersions":"cannotmatch","vulnerabilityType":"Critical software","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-61898","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-61898","en":"https://www.redsauce.net/en/cves/CVE-2026-61898","fr":"https://www.redsauce.net/fr/cves/CVE-2026-61898","pt":"https://www.redsauce.net/pt/cves/CVE-2026-61898","de":"https://www.redsauce.net/de/cves/CVE-2026-61898","sk":"https://www.redsauce.net/sk/cves/CVE-2026-61898","el":"https://www.redsauce.net/el/cves/CVE-2026-61898"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-61898"}}
