CVE-2022-45414
CVSS v2.0
9.4
High
| Vector | AV:N/AC:L/Au:N/C:C/I:C/A:N |
Name of the Vulnerable Software and Affected Versions
Thunderbird versions prior to 102.5.1
Description
The issue is related to the handling of HTML emails in Thunderbird. When a user quotes from an HTML email, for example by replying to it, and the email contains certain tags like VIDEO with the POSTER attribute or OBJECT with a DATA attribute, a network request to the referenced remote URL is performed. This happens regardless of the configuration to block remote content. An image loaded from the POSTER attribute is shown in the composer window. This could give an attacker additional capabilities.
Recommendations
For versions prior to 102.5.1, update to version 102.5.1 or later to resolve the issue. As a temporary workaround, consider avoiding quoting from HTML emails that contain VIDEO or OBJECT tags until the update is applied. Restrict access to remote content in the email client settings to minimize the risk of exploitation.
