EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2024-34067 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,636 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Pterodactyl is a free, open-source game server management panel built with PHP, React, and Go. Importing a malicious egg or gaining access to wings instance could lead to cross site scripting (XSS) on the panel, which could be used to gain an administrator account on the panel. Specifically, the following things are impacted: Egg Docker images and Egg variables: Name, Environment variable, Default value, Description, Validation rules. Additionally, certain fields would reflect malicious input, but it would require the user knowingly entering such input to have an impact. To iterate, this would require an administrator to perform actions and can't be triggered by a normal panel user. This issue has has been addressed in version 1.11.6 and users are advised to upgrade. No workaround is available other than updating to the latest version of the panel.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pterodactyl/panel, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update pterodactyl/panel to 1.11.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-34067 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2024-34067 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2024-34067. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
