CVE intelligence and bounded remediation

CVE-2024-9107 — A stored cross-site scripting (XSS) vulnerability exists in the gaizhenbiao/chuanhuchatgpt repository, affecting version git 20b2e02

Medium CVSS 6.8

A stored cross-site scripting (XSS) vulnerability exists in the gaizhenbiao/chuanhuchatgpt repository, affecting version git 20b2e02. The vulnerability arises from improper sanitization of HTML tags in chat history uploads. Specifically, the sanitization logic fails to handle HTML tags within code blocks correctly, allowing an attacker to inject malicious scripts. This can lead to the execution of arbitrary JavaScript code in the context of the user's browser, potentially leading to identity theft or other malicious actions.

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.
