| Vector | AV:N/AC:M/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 69
Firefox ESR versions prior to 68.1
Description
The issue is related to Content Security Policy (CSP) directives that use hash-based sources. If such a directive is defined with an empty string as input, it allows the execution of any javascript: URIs, potentially bypassing CSP permissions and enabling malicious JavaScript content to run. This could allow a remote attacker to execute arbitrary code.
Recommendations
For Firefox versions prior to 69, update to version 69 or later to resolve the issue.
For Firefox ESR versions prior to 68.1, update to version 68.1 or later to resolve the issue.
