Is this vulnerability remotely exploitable over the network?

Yes. An attacker who can position themselves as a man-in-the-middle on the network path between Parsec Web clients can remotely exploit the weakness during the Diffie–Hellman key exchange.

What level of access does an attacker need to exploit this issue?

The attacker needs active on-path capabilities, such as control over a network gateway, router, or Wi‑Fi access point. Passive eavesdropping alone is insufficient; the attacker must be able to intercept and modify key exchange messages.

What is the safest general fix pattern for developers?

The safest pattern is to ensure strict validation of all elliptic-curve public keys before use, rely on well-audited cryptographic libraries that enforce subgroup and point checks by default, and avoid custom cryptographic glue code that bypasses built-in safeguards.
