{"apiVersion":"1.0","identifier":"CVE-2026-73849","description":"Emlog is an open source website building system. In 2.6.26 and earlier, install.php accepts action=reinstall without authentication and deliberately skips the already-installed check because the guard runs only when $act != -reinstall-. A remote attacker can submit hostname, dbuser, dbpasswd, dbname, dbprefix, username, password, and email values to cause file_put_contents(-config.php-, $config) to overwrite the configuration with attacker-controlled database settings and create a new administrator account. No fixed version is available as of this review.","publishedAt":"2026-08-14T18:19:09","lastModifiedAt":"2026-08-18T02:17:30","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73849","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00484,"riskScore":1.02,"affectedProduct":"Emlog","affectedVersions":"<=2.6.26","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73849","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73849","en":"https://www.redsauce.net/en/cves/CVE-2026-73849","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73849","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73849","de":"https://www.redsauce.net/de/cves/CVE-2026-73849","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73849","el":"https://www.redsauce.net/el/cves/CVE-2026-73849"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73849"}}
