CVE-2022-26382

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 98

Description The issue is related to the Autofill tooltips in Firefox, where the text displayed cannot be directly read by JavaScript but is rendered using page fonts. This could lead to side-channel attacks using specially crafted fonts, potentially allowing an attacker to infer the text. The vulnerability is associated with a lack of protection for sensitive data, which could enable an unauthorized party to access protected information.

Recommendations For versions prior to 98, update to version 98 or later to resolve the issue. As a temporary workaround, consider restricting the use of Autofill tooltips until a patch is applied. Avoid using specially crafted fonts that could be used in side-channel attacks.
