Technical description

The embedded HTTP server does not clear the security identity established during a request before its worker thread handles the next request. A remote unauthenticated attacker can have their request processed with the identity of a previously authenticated user, gaining that user's privileges. Only applications served by the embedded HTTP server that authenticate programmatically or via basic authentication are affected. Users are recommended to block network access to the embedded HTTP server from untrusted clients, or to migrate to the Tomcat based TomEE distributions.

——0pgEdge RAG Server is an API server for retrieval-augmented generation over PostgreSQL content using pgvector. Prior to 2.0.0, the BM25 keyword index is a single per-pipeline object shared by the unauthenticated query endpoint, and concurrent requests lock its clear, refill, and search operations separately. This allows one request to search a corpus populated through another request's search filter, which can return documents belonging to a different tenant or customer without malformed input. The affected responses cannot be identified retrospectively from the server logs. This issue is fixed in version 2.0.0.12h CVE-2026-111245—

——0After a successful WS-Security UsernameToken authentication, the caller identity stays associated with the worker thread once the request completes when web services are served by the standalone OpenEJB HTTP server. A remote unauthenticated attacker whose request is later processed on the same thread can invoke protected EJB methods with the identity of a previously authenticated user. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.14h CVE-2026-111242—

——0When MicroProfile JWT authentication is used for servlets that declare a run-as identity, the security state established for a request is not always cleared from the processing thread when the request does not complete normally. A remote attacker holding a valid token can cause later, unrelated requests served by the same thread to invoke enterprise beans with the elevated run-as identity. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.14h CVE-2026-1222333.7 LOW

——4FrankenPHP before 1.13.4 contains an information disclosure vulnerability in worker mode that fails to clear last HTTP stream response headers between requests, because the reset only happens in RSHUTDOWN, which worker requests skip. Later requests calling http_get_last_response_headers() can read headers fetched by earlier requests on the same worker thread, exposing other users' Set-Cookie or token headers from backend APIs.2d CVE-2026-1219668.7 HIG

——8Traefik 2.x before 2.11.60 and 3.x before 3.7.16 sends ForwardAuth subrequests (and, in 3.7, Ingress NGINX auth-url requests) through an auth-server connection pool shared by all clients, exposing connection-bound NTLM or Negotiate authentication. An unauthenticated attacker can reuse another user's authenticated connection, receiving the victim's identity via authResponseHeaders to access backends as that user.6d CVE-2026-1206346.5 MED

——9CGI::Carp versions before 5.00 for Perl leak warnings across requests in persistent environments via the warningsToBrowser buffer. Warnings are held in a package-level buffer until warningsToBrowser writes them into the page as HTML comments, and the buffer is never cleared between requests. Under mod_perl, FastCGI or PSGI, warnings from one request are written into a later one. Warnings that contain one user's request data can appear in the HTML sent to another user.1d
