    "title": "Apache Roller: Reflected cross-site scripting in the frontpage directory parameter",
    "summary": "Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.5 allows a remote attacker to perform reflected cross-site scripting against a visitor to a weblog using the bundled frontpage theme, by supplying a crafted blog-directory parameter that the directory page reflects without proper escaping. This affects only weblogs that use the bundled frontpage theme, and a victim must follow a crafted link for the script to execute. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which validates and contextually escapes the reflected parameter.",
