CVE-2020-15666 (GCVE-0-2020-15666)

Vulnerability from cvelistv5 – Published: 2020-10-01 18:42 – Updated: 2024-08-04 13:22

Summary

When trying to load a non-video in an audio/video context the exact status code (200, 302, 404, 500, 412, 403, etc.) was disclosed via the MediaError Message. This level of information leakage is inconsistent with the standardized onerror/onsuccess disclosure and can lead to inferring login status to services or device discovery on a local network among other attacks. This vulnerability affects Firefox < 80 and Firefox for Android < 80.

Severity
