CVE-2025-13015Public exploitNetwork attack vector

Link-destination spoofing via unescaped bidi controls

Published Nov 11, 2025 · Updated Apr 13, 2026

URL spoofing in Mozilla Firefox before 145 and Firefox ESR before 115.30 or 140.5 allows remote attackers to disguise link targets. The status-panel formatter decodes URLs without escaping LRI, PDI, and ALM bidirectional controls, allowing visible text to reorder into a false domain. A victim must hover over an attacker-supplied link and then follow it; the preview can show a trusted domain while navigation reaches another domain.
