CVE-2024-11824 is a high-severity Cross-site Scripting (CWE-79) vulnerability in Langgenius Dify. Its CVSS base score is 7.6 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Browser Session Hijacking (T1185); ranked at the 37th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
This vulnerability is AI-related — categorised as LLM Application Platforms; in the Privacy and Disclosure risk domain.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-11824 is a stored cross-site scripting (XSS) vulnerability in the langgenius/dify application, specifically within its chat log functionality. The flaw affects the latest version prior to the patch and occurs because certain HTML tags, such as <input> and <form>, are not properly disallowed. This allows attackers to inject malicious HTML into chat logs via prompts. The vulnerability carries a CVSS v3.1 base score of 7.6 (AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N) and maps to CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting').
A low-privileged user (PR:L) can exploit the vulnerability by submitting prompts containing malicious HTML, which becomes stored in the chat log. When an administrator views the tainted log, the injected script executes in the admin's browser context due to insufficient sanitization, enabling the attacker to steal the admin's credentials or other sensitive information. Exploitation requires network access and user interaction from the victim (UI:R), but achieves high confidentiality impact with changed scope (S:C).
The issue is addressed in Dify version 0.12.1, with the fix implemented in commit 55edd5047e6fcbc9bb56a4ea055fcce090f3eb5d available at https://github.com/langgenius/dify/commit/55edd5047e6fcbc9bb56a4ea055fcce090f3eb5d. Security teams should prioritize upgrading to the patched version. Further details, including the original report, are provided in the Huntr bounty advisory at https://huntr.com/bounties/72387deb-6e64-48ed-a8c3-b50d22a0970f.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect input neutralization through targeted web-application tests.
Input validation directly enforces neutralization of untrusted data before it reaches web output generation.
Output filtering can catch or sanitize unneutralized script content before it is served to users.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).
Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).

Secure-coding testing and automated code-analysis tools are applied to detect improper neutralization of script-related content during web-page generation.
Knowledge exchange on emerging attack techniques and patches reduces the likelihood that cross-site scripting flaws remain unaddressed in deployed applications.
Operational indicators of compromise for web-application attacks can be incorporated into WAF or input-filtering rules, lowering the likelihood that unsanitized data reaches the browser.
Requiring language-specific secure-coding standards and automated scanning during the SDLC catches missing output encoding or improper neutralization of untrusted data before the software reaches production.
Secure-coding standards, SAST scans and removal of insecure code samples together eliminate the failure to neutralize script content that produces cross-site scripting flaws.
Webpage malware scanning and block-listing of known malicious sites reduce the likelihood that reflected or stored script payloads reach a user’s browser.
