  "summary" : "Eclipse Jetty: Early return from the JASPIAuthenticator code can potentially no clear ThreadLocal variables",
  "details" : "### Description (as reported)\n\nA security vulnerability has been identified in Jetty's  `JaspiAuthenticator.java`. \n\nThe root cause is a failure to consistently clear authentication metadata stored in  `ThreadLocal`  during certain error or incomplete authentication flows. \nSpecifically, after a `GroupPrincipalCallback`  is persisted into the  `ThreadLocal`, the authentication process may exit prematurely — before the  `ThreadLocal`  storage is cleared — if a mandatory `CallerPrincipalCallback`  is missing or an exception occurs. \nThis allows a subsequent, unprivileged user processed by the same worker thread to inherit these residual security roles, leading to Broken Access Control and Privilege Escalation.\n\nSee also attached PDF.\n\n### Impact\nAn unauthenticated user may gain ungrated privileges from a previous request (privilege escalation).\n\n### Patches\nNo patches yet.\n\n### Workarounds\nDo not use Jetty's JASPI.",
