Name of the Vulnerable Software and Affected Versions LibreOffice Calc (affected versions not specified)

Description LibreOffice Calc allows linking a cell range to an external csv data source, with the link being saved within the document. Because these links are fetched during the document loading process, opening a malicious document can lead to Local File Inclusion (LFI), where a local file is read into the sheet, or Server-Side Request Forgery (SSRF), where a request is made to a host selected by the document creator. This occurs via calcext:data-mappings and the csv provider.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
