Name of the Vulnerable Software and Affected Versions GitHub Enterprise Server versions prior to 3.21
Description An unauthenticated attacker can cause excessive CPU consumption and exhaust the pool of request-handling worker processes by sending a crafted form-encoded HTTP POST request containing deeply nested parameters. Since request parameters are parsed before routing and authentication, any POST endpoint can be used to trigger this condition, potentially rendering the instance unresponsive.
Recommendations Update to version 3.20.3 Update to version 3.19.7 Update to version 3.18.10 Update to version 3.17.16
