Doc Text:	A flaw was found in DBD::File. The `complete_table_name` method, responsible for building absolute table file paths, does not verify if the file is a symbolic link. This oversight allows a local attacker to create a symbolic link within the data directory that points to an arbitrary file outside of the intended data storage. Consequently, file-based drivers can be tricked into reading from or writing to unauthorized files, potentially leading to information disclosure or data corruption.	Story Points:	---

Description OSIDB Bzimport 2026-07-14 16:03:06 UTC

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.
