CVE-2026-15392

EUVD-2026-43727

14.07.2026, 16:16

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.

Common Weakness Enumeration

CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
