USN-9060-1: kramdown flaw may allow arbitrary file reads or code execution
An Ubuntu Security notice says kramdown processed the template option by default in documents, which an attacker could possibly use to read arbitrary files or execute arbitrary code.
Notice USN-9060-1, published on 11 November 2026 in the Ubuntu Security feed, describes a vulnerability in kramdown, a Markdown text conversion library used in many projects. According to the text, kramdown processed the template option by default in documents. An attacker could possibly exploit this behavior to read arbitrary files on the system or execute arbitrary code. The text provided is an automatic translation of the original notice, so technical details, affected versions and the recommended fix must be checked directly at the official Ubuntu Security source. To verify, open the original notice through the Ubuntu security channel, check whether the kramdown package is installed on your systems, and compare its version with the one recommended in the notice. If your application converts documents sent by third parties, treat that path as a priority. This item is not a Rota Nacional tutorial, and the received text does not state that the platform patches the library.
