Cross-site scripting (XSS) vulnerability in MyBulletinBoard (MyBB) allows remote attackers to inject arbitrary web script or HTML via a signature containing a JavaScript URI in the SRC attribute of an IMG element, in which the URI uses SGML numeric character references without trailing semicolons, as demonstrated by "&#106&#97&#118&#97&#115&#99&#114&#105&#112&#116".

Security readout for executives and security teams

CVE-2006-0364 is an old cross-site scripting issue in MyBulletinBoard/MyBB signatures. A malicious signature could cause script or HTML to run in another user's browser when viewed. The bundle does not identify affected versions, CVSS severity, a patch, or current exploitation. Exposure is likely limited to legacy MyBB/MyBulletinBoard installations that allowed HTML or image tags in user signatures. Organizations without MyBB, or with signature HTML disabled and modern patched versions, are less likely to be affected. Treat this as a legacy exposure check, not an emergency, unless MyBB forums remain internet-facing and allow rich HTML signatures. Business risk is user session compromise or trust damage through forum-based script execution. Mitigation focus: Inventory any legacy MyBB or MyBulletinBoard deployments.; Check official MyBB or vendor guidance for affected versions and fixes.; Disable or tightly sanitize HTML in user signatures..
