### Impact An attacker who can MITM the TLS connection between the client and the IDP (within the TI network) can substitute a forged discovery document. The forged document redirects u ri_puk_idp_enc and uri_puk_idp_sig to attacker-controlled URLs. The client then encrypts the SMC-B-signed challenge response to the attacker's encryption key and POSTs it to the attacker's auth endpoint. This captures the signed authentication material. ### Patches [#36](https://github.com/oviva-ag/epa4all-client/pull/36) ### Workarounds None. ### Resources - MS-OVIVA-EPA4ALL-d453c1 ### Credits [Machine Spirits](https://machinespirits.com/) ([[email protected]](mailto:[email protected])) - Dr. rer. nat.

AI coding agents often install or upgrade packages automatically in maven. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
