There is no fixed version for Debian:13 smarty3.
NVD Description
Note: Versions mentioned in the description apply only to the upstream smarty3 package and not the smarty3 package as distributed by Debian.
See How to fix? for Debian:13 relevant fixed versions and status.
Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. Prior to 5.8.2 (and 4.5.7 on the 4.x line), Security::_checkDir() does not fully resolve symbolic links before validating that a requested path lies within a configured secure directory. An attacker able to place or reference a symlink within a directory Smarty treats as trusted (e.g., a template or config directory) could use it to point outside the intended secure directory, bypassing the containment check and reading arbitrary files accessible to the PHP process. This issue is fixed in versions 5.8.2 and 4.5.7.
