Description OSIDB Bzimport 2026-04-23 16:47:55 UTC 
A flaw was found in libcurl. Due to a logical error in the connection reuse mechanism for SMB (Server Message Block) transfers, libcurl might reuse an existing SMB connection with a different share than intended. This vulnerability, categorized as CWE-488 (Exposure of Data Element to Wrong Session), could lead to the download of an incorrect file or the upload of a file to an unintended location when an application uses libcurl for SMB transfers.
