CVE-2016-5262 describes a cross-site scripting (XSS) vulnerability in Mozilla Firefox versions prior to 48.0 and Firefox ESR 45.x before 45.3. This flaw allows remote attackers to conduct XSS attacks by exploiting how JavaScript event-handler attributes of a MARQUEE element are processed within sandboxed IFRAMEs lacking the "allow-scripts" attribute. With a CVSS score of 6.1 (Medium), this vulnerability requires user interaction (UI:R) and has low impact on confidentiality and integrity (C:L/I:L). There is no evidence of active exploitation, publicly available exploit code, or significant community discussion, suggesting a low current threat level.
