#CVE-2023-3417: File Extension Spoofing using the Text Direction Override Character
- Reporter
- 이준성 (Junsung Lee)

Thunderbird allowed the Text Direction Override Unicode Character in filenames. An email attachment could be incorrectly shown as being a document file, while in fact it was an executable file. Newer versions of Thunderbird will strip the character and show the correct file extension.
