CVE-2026-9318 with a CVSS score of 5.4 is a stored cross-site scripting vulnerability in the tablib library that allows attackers to execute arbitrary JavaScript by embedding malicious payloads in dataset titles, which are interpolated unsanitized into HTML output via the export_book method in the _html.py format handler. Attackers can rename worksheet sheets in imported files such as XLSX, ODS, XLS, or YAML with script payloads that are assigned to the Dataset title attribute and rendered unescaped inside an HTML h3 tag, leading to session hijacking, unauthorized administrative actions, and sensitive data exposure when the output is rendered in a browser. The vulnerability affects versions of tablib prior to 3.10.0, allowing attackers to inject malicious JavaScript code into exported HTML files, which can then be executed by unsuspecting users when they view the files in a web browser.
We recommend you to update tablib to version 3.10.0.[/subscribe_to_unlock_form]
