The Theron Lite theme for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘url’ parameter within the theme's Button shortcode in all versions up to, and including, 2.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Heron versions <= 0.20.4-incubating allows CRLF log injection because of the lack of escaping in the log statements. Please update to version 0.20.5-incubating which addresses this issue.

It was noticed that Apache Heron 0.20.2-incubating, Release 0.20.1-incubating, and Release v-0.20.0-incubating does not configure its YAML parser to prevent the instantiation of arbitrary types, resulting in a remote code execution vulnerabilities (CWE-502: Deserialization of Untrusted Data).

When accessing the heron-ui webpage, people can modify the file paths outside of the current container to access any file on the host. Example woule be modifying the parameter path= to go to the directory you would like to view. i.e. ..%2F..%2F..%2F..%2F..%2F..%2Fetc%2Fpasswd.
