ODF documents can contain forms to be filled out by the user. Similar to HTML forms, the contained form data can be submitted to a URI, for example, to an external web server. To create submittable forms, ODF implements the XForms W3C standard, which allows data to be submitted without the need for macros or other active scripting Prior to version 6.4.4 LibreOffice allowed forms to be submitted to any URI, including file: URIs, enabling form submissions to overwrite local files. User-interaction is required to submit the form, but to avoid the possibility of malicious documents engineered to maximize the possibility of inadvertent user submission this feature has now been limited to http[s] URIs, removing the possibility to overwrite local files. This issue affects: The Document Foundation LibreOffice versions prior to 6.4.4.

CVE-2022-3140 [MEDIUM] LibreOffice vulnerabilities
Title: LibreOffice vulnerabilities
Summary: Several security issues were fixed in LibreOffice.
It was discovered that LibreOffice incorrectly handled links using the
Office URI Schemes. If a user were tricked into opening a specially
crafted document, a remote attacker could use this issue to execute
arbitrary scripts. (CVE-2022-3140)
Thomas Florian discovered that LibreOffice incorrectly handled crashes when
an encrypted document is open. If the document is recovered upon restarting
LibreOffice, subsequent saves of the document were unencrypted. This issue
only affected Ubuntu 18.04 LTS. (CVE-2020-12801)
Jens Müller discovered that LibreOffice incorrectly handled certain
documents containing forms. If a user were tricked into opening a specially
