High

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 76

Description Documents formed using data: URLs in an OBJECT element failed to inherit the Content Security Policy (CSP) of the creating context. This allowed the execution of scripts that should have been blocked, albeit with a unique opaque origin.

Recommendations For versions prior to 76, update to version 76 or later to resolve the issue. As a temporary workaround, consider restricting the use of data: URLs in OBJECT elements to minimize the risk of exploitation.
