CVE-2026-15392 Details
Description
DBD::File versions before 1.651 for Perl do not ensure the table file is not a symlink to an untrusted location. The complete_table_name method builds the absolute table file path without checking whether the file is a symbolic link. A link inside the data directory can point to a table file at any path outside of the configured f_dir and f_dir_search directories. Callers of file-based drivers can read or write files outside of the data directory.
A vulnerability exists in the DBD::File module for Perl, specifically in versions prior to 1.651. The issue arises because the module's complete_table_name method does not verify whether a table file is a symbolic link, allowing links to point to untrusted locations. This flaw enables file-based drivers to read from or write to files outside the designated data directory, potentially leading to unauthorized file access or modification.
Users should update to DBD::File version 1.651 or later, where this vulnerability has been fixed.
