Impact

A malicious user can trigger a user logout if a signed in user visits a malicious website that makes a request to the Panel's sign-out endpoint. This requires a targeted attack against a specific Panel instance, and serves only to sign a user out. No user details are leaked, nor is any user data affected, this is simply an annoyance at worst.

A victim's authenticated browser session is used to submit forged requests to an application that cannot distinguish them from legitimate ones. Typical impact: state-changing actions performed as the victim without their consent.

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions

  1. What is CVE-2021-41176? CVE-2021-41176 is a low-severity cross-site request forgery (CSRF) vulnerability in pterodactyl/panel (composer), affecting versions >= 1.0.0, < 1.6.3. It is fixed in 1.6.3. A victim's authenticated browser session is used to submit forged requests to an application that cannot distinguish them from legitimate ones.
  2. Which versions of pterodactyl/panel are affected by CVE-2021-41176? pterodactyl/panel (composer) versions >= 1.0.0, < 1.6.3 is affected.
  3. Is there a fix for CVE-2021-41176? Yes. CVE-2021-41176 is fixed in 1.6.3. Upgrade to this version or later.
  4. Is CVE-2021-41176 exploitable, and should I be worried? Whether CVE-2021-41176 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

  5. What actually determines whether CVE-2021-41176 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
  6. How do I fix CVE-2021-41176? Upgrade pterodactyl/panel to 1.6.3 or later.
