CVE-2020-6824 (GCVE-0-2020-6824)

Vulnerability from cvelistv5 – Published: 2020-04-24 15:52 – Updated: 2024-08-04 09:11

Summary

Initially, a user opens a Private Browsing Window and generates a password for a site, then closes the Private Browsing Window but leaves Firefox open. Subsequently, if the user had opened a new Private Browsing Window, revisited the same site, and generated a new password - the generated passwords would have been identical, rather than independent. This vulnerability affects Firefox < 75.

Severity

No CVSS data available.

CWE

Generated passwords may be identical on the same site between separate private browsing sessions

Assigner
