CVE-2023-5720
HIGHCVE-2023-5720 is a high-severity (CVSS 7.7) CWE-526 vulnerability in io.quarkus:quarkus-project. O3 Security confirms whether CVE-2023-5720 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Quarkus: build env information disclosure via gradle plugin
Real-World Exposure
io.quarkus:quarkus-projectReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
A flaw was found in Quarkus, where it does not properly sanitize artifacts created using the Gradle plugin, allowing certain build system information to remain. This flaw allows an attacker to access potentially sensitive information from the build system within the application.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | io.quarkus:quarkus-project | ≥ 3.0.0.CR1 | No fix |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.quarkus:quarkus-project. 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 io.quarkus:quarkus-project has shipped for CVE-2023-5720 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-2023-5720 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-2023-5720. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-5720 in your dependencies?
O3 detects CVE-2023-5720 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
