GHSA-XWWR-4H3P-R22C rclone serve s3: --auth-proxy without --auth-key authenticates nobody - full SigV4 signature bypass

Summary rclone serve s3's handler chain, when --auth-proxy is configured, is outermost first: authPairMiddleware - proxyAuthMiddleware - gofakes3's own SigV4-verifying handler. authPairMiddleware parses the accessKeyID straight out of the incoming request's own Authorization header entirely...

CVE-2026-88018

rclone (a command-line tool for syncing files to cloud storage) contains a SigV4 signature bypass in its serve s3 mode. When configured with --auth-proxy but without --auth-key, the authPairMiddleware registers any client-chosen accessKeyID with an empty secret. The embedded gofakes3 component th...

PT-2026-89681

Summary In streamed multipart mode, serve s3 passes the request's declared part length to multipart.NewRW.ReservecontentLength before reading any part data. Reserve immediately obtains enough 1 MiB pool pages for the entire declared length. The request handler therefore allocates attacker-selecte...
