rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.70.0 until 1.75.1, the serve/start RC interface accepts per-server proxyOpt.AuthProxy settings, and the FTP and S3 constructors in cmd/serve/ftp/ftp.go and cmd/serve/s3/server.go...

CVE-2026-88044

rclone versions 1.70.0 through 1.75.1 are affected by an authentication proxy bypass in the serve/start RC interface. The FTP and S3 constructors in cmd/serve/ftp/ftp.go and cmd/serve/s3/server.go incorrectly check the process-global proxy.Opt.AuthProxy value instead of the per-server request-loc...

CVE-2026-88017

rclone versions 1.64.0 through 1.75.1 contain a cross-session authentication confusion in the FTP auth-proxy driver (cmd/serve/ftp/ftp.go). The server stores one obscured password per username in a global userPass map rather than binding it to the authenticated session. When a second login with t...

CVE-2026-88011 Traefik: ForwardAuth identity spoofing via dot-form header alias

Traefik is an open source HTTP reverse proxy and load balancer. Prior to 2.11.56, and from 3.0.0 until 3.7.12, a client-supplied dot-form header such as X.Authenticated.User survives ForwardAuth replacement and underscoreHeadersStrategy because Go treats it as distinct from X-Authenticated-User...

CVE-2026-88011

Traefik 's ForwardAuth middleware is vulnerable to identity spoofing via dot-form header aliases (e.g. X.Authenticated.User). Go treats these as distinct from the canonical dash-form header, but backends such as PHP, CGI, WSGI, and NGINX collapse both into the same variable, allowing a permitted ...
