Published:August 04, 2026
Updated:August 05, 2026
In Eclipse Milo versions 0.6.0 through 1.1.4, username-token processing returns distinguishable errors for invalid RSA PKCS#1 v1.5 padding and other authentication failures, allowing an on-path attacker who captures a victim's "Basic128Rsa15"-encrypted username token to use repeated unauthenticated "ActivateSession" requests as a padding oracle, recover the victim's password, and authenticate with the recovered credentials.
