CVE-2023-50256 is a high-severity (CVSS 7.5) Improper Input Validation vulnerability in froxlor/froxlor. 2 public exploit references exist, so weaponization risk is real. O3 Security confirms whether CVE-2023-50256 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Froxlor username/surname AND company field Bypass
Real-World Exposure
froxlor/froxlorReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Froxlor is open source server administration software. Prior to version 2.1.2, it was possible to submit the registration form with the essential fields, such as the username and password, left intentionally blank. This inadvertent omission allowed for a bypass of the mandatory field requirements (e.g. surname, company name) established by the system. Version 2.1.2 fixes this issue.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | froxlor/froxlor | all versions | 2.1.2 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for froxlor/froxlor. 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.
Fix
Update froxlor/froxlor to 2.1.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-50256 is resolved across your whole dependency graph.
Workarounds
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-2023-50256 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-2023-50256. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
