CVE-2024-7990
HIGHCVE-2024-7990 is a high-severity (CVSS 8.4) Cross-site Scripting (XSS) vulnerability in open-webui. O3 Security confirms whether CVE-2024-7990 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Stored Cross-Site Scripting in open-webui/open-webui
Real-World Exposure
open-webuiReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
A stored cross-site scripting (XSS) vulnerability exists in open-webui/open-webui version 0.3.8. The vulnerability is present in the /api/v1/models/add endpoint, where the model description field is improperly sanitized before being rendered in chat. This allows an attacker to inject malicious scripts that can be executed by any user, including administrators, potentially leading to arbitrary code execution.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for open-webui. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of open-webui has shipped for CVE-2024-7990 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2024-7990 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2024-7990. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
