CVE-2023-6186

Script execution via unchecked hyperlink macro targets

Published Dec 11, 2023 · Updated Feb 13, 2025

Improper macro permission validation in LibreOffice 7.5 before 7.5.9 and 7.6 before 7.6.4 allows attackers to execute built-in macros. Hyperlink targets for macros and internal commands bypass the document macro-permission check when activated. Exploitation requires a user to activate a crafted hyperlink, after which code runs with that user's LibreOffice privileges.
