Remediation

Fix status not established

No structured fix or guidance is available here. Check the latest publisher advisory.

What this means

Tablib versions prior to 3.10.0 have a stored cross-site scripting vulnerability in HTML export, allowing attackers to execute JavaScript via malicious dataset titles. Attackers need access to rename worksheet sheets with script payloads. This may lead to session hijacking or data exposure when output is rendered in a browser.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Original source description

Read the full publisher description

tablib prior to 3.10.0 contains a stored cross-site scripting vulnerability in the HTML export functionality 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.
