Mozilla Foundation Security Advisory 2022-50
Security Vulnerabilities fixed in Thunderbird 102.5.1
Announced: November 30, 2022
Impact: moderate
Products: Thunderbird
Fixed in: Thunderbird 102.5.1
# CVE-2022-45414: Quoting from an HTML email with certain tags will trigger
network requests and load remote content, regardless of a configuration to
block remote content
Reporter: Sarah Jamie Lewis
Impact: moderate
Description
If a Thunderbird user quoted from an HTML email, for example by replying to the
email, and the email contained either a VIDEO tag with the POSTER attribute or
an OBJECT tag with a DATA attribute, a network request to the referenced remote
URL was performed, regardless of a configuration to block remote content. An
image loaded from the POSTER attribute was shown in the composer window. These
issues could have given an attacker additional capabilities when targetting
releases that did not yet have a fix for CVE-2022-3033 which was reported
around three months ago.
