{"apiVersion":"1.0","identifier":"CVE-2026-45124","description":"MyBB is free and open source forum software. Prior to 1.8.40, the Mod CP Report Center does not check permissions consistently, allowing moderators without report-management permission to mark reports as resolved. The modcp.php?action=do_reports Mark Selected as Read handler is reachable with canmodcp even without canmanagereportedcontent or canmanagereportedposts. When no forums are in scope, $flist_reports is empty and the UPDATE mybb_reportedcontent query executes without the expected permission-based limitation. This issue is fixed in version 1.8.40.","publishedAt":"2026-08-18T16:17:07","lastModifiedAt":"2026-08-19T15:17:03","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-45124","cvssScore":4.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","epssProbability":0.00246,"riskScore":0.44,"affectedProduct":"MyBB","affectedVersions":"<1.8.40","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-45124","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-45124","en":"https://www.redsauce.net/en/cves/CVE-2026-45124","fr":"https://www.redsauce.net/fr/cves/CVE-2026-45124","pt":"https://www.redsauce.net/pt/cves/CVE-2026-45124","de":"https://www.redsauce.net/de/cves/CVE-2026-45124","sk":"https://www.redsauce.net/sk/cves/CVE-2026-45124","el":"https://www.redsauce.net/el/cves/CVE-2026-45124"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-45124"}}
