Open WebUI Uncontrolled Resource Consumption vulnerability
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 vulnerability in open-webui/open-webui v0.3.8 allows an unauthenticated attacker to sign up with excessively large text in the 'name' field, causing the Admin panel to become unresponsive. This prevents administrators from performing essential user management actions such as deleting, editing, or adding users. The vulnerability can also be exploited by authenticated users with low privileges, leading to the same unresponsive state in the Admin panel.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for open-webui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of open-webui has shipped for GHSA-wcwp-9rcp-jvfg 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-wcwp-9rcp-jvfg can be triaged on real exposure rather than presence alone.
Tailored to GHSA-wcwp-9rcp-jvfg. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
