Pips keeps an identity key on the device and checks signatures on everything it receives, so flaws in parsing or cryptography matter.
Please report vulnerabilities privately through GitHub: Security → Report a vulnerability on this repository. Do not open a public issue.
In scope: the crates in crates/ (parsers, signatures, certificates,
envelopes, backups) and the app in web/ (key storage, CSP, anything a
received code or file can make it do).
