CVE-2024-3851 — Pribai Privategpt security vulnerability
A stored Cross-Site Scripting (XSS) vulnerability exists in the 'imartinez/privategpt' repository due to improper validation of file uploads. Attackers can exploit this vulnerability by uploading malicious HTML files, such as those containing JavaScript payloads, which are then executed in the context of the victim's session when accessed. This could lead to the execution of arbitrary JavaScript code in the context of the user's browser session, potentially resulting in phishing attacks or other malicious actions.

Matched remediation archetype
Cross-site scripting and unsafe browser output
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
- Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
- Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.
Remediate safely
- Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
- Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
- Update affected rendering components and add tests for every output context using inert sentinel markup.
