**Name of the Vulnerable Software and Affected Versions** Thunderbird versions prior to 60.9 Thunderbird versions prior to 68.1 **Description** The issue is related to the Secure/Multipurpose Internet Mail Extensions (S/MIME) functionality in the Thunderbird email client, specifically concerning the lack of protection for certain data. This could allow a remote attacker to gain unauthorized access to protected information. Additionally, it is noted that encrypted S/MIME parts in a crafted multipart/alternative message can leak plaintext when included in an HTML reply or forward. **Recommendations** For versions prior to 60.9, update to version 60.9 or later. For versions prior to 68.1, update to version 68.1 or later.

**Name of the Vulnerable Software and Affected Versions** Thunderbird versions prior to 52.9 **Description** The issue is related to the Secure/Multipurpose Internet Mail Extensions (S/MIME) function in the Thunderbird email client, which lacks protection for certain data. This can allow a remote attacker to gain unauthorized access to protected information when an email is forwarded or replied to. Specifically, decrypted S/MIME parts that are hidden using CSS or the plaintext HTML tag can leak plaintext when included in an HTML reply or forward. **Recommendations** For versions prior to 52.9, update to version 52.9 or later to resolve the issue. As a temporary workaround, consider avoiding the use of HTML replies or forwards for emails containing sensitive S/MIME-protected information until the update is applied.

**Name of the Vulnerable Software and Affected Versions** Thunderbird versions prior to 52.9 **Description** The issue is related to the decryption of S/MIME parts in HTML messages, which can lead to plaintext leakage when included in a reply or forward. This is due to a lack of protection for certain data in the S/MIME and PGP functions of the Thunderbird email client. An attacker can exploit this issue by manipulating HTML messages to gain unauthorized access to protected information. **Recommendations** For versions prior to 52.9, update to version 52.9 or later to resolve the issue. As a temporary workaround, consider avoiding the use of HTML replies or forwards for sensitive messages until the update is applied. Restrict access to sensitive information when using the affected Thunderbird versions to minimize the risk of exploitation.
