Versions of st prior to 0.2.5 are affected by a directory traversal vulnerability. Vulnerable versions fail to properly handle URL encoded dots, which caused %2e to be interpreted as . by the filesystem, resulting the potential for an attacker to read sensitive files on the server.

Recommendation

Update to version 0.2.5 or later.
