{"apiVersion":"1.0","identifier":"CVE-2026-45129","description":"MyBB is free and open source forum software. Prior to 1.8.40, the Admin CP Recovery Codes module does not validate requests correctly, allowing same-site attackers to rotate a victim administrator-s recovery codes with a specially crafted URL. The Admin CP Home, Preferences, Recovery Codes action=recovery_codes page regenerates Two-Factor Authentication recovery codes in mybb_adminoptions.recovery_codes on GET requests without request forgery protection. The uniquely identifying implementation details include admin/modules/home/preferences.php. This issue is fixed in version 1.8.40.","publishedAt":"2026-08-18T16:17:08","lastModifiedAt":"2026-08-18T19:16:50","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-45129","cvssScore":4.6,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:L","epssProbability":0.00139,"riskScore":0.47,"affectedProduct":"MyBB","affectedVersions":"<1.8.40","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-45129","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-45129","en":"https://www.redsauce.net/en/cves/CVE-2026-45129","fr":"https://www.redsauce.net/fr/cves/CVE-2026-45129","pt":"https://www.redsauce.net/pt/cves/CVE-2026-45129","de":"https://www.redsauce.net/de/cves/CVE-2026-45129","sk":"https://www.redsauce.net/sk/cves/CVE-2026-45129","el":"https://www.redsauce.net/el/cves/CVE-2026-45129"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-45129"}}
