Does this matter?
Lower severity and a low EPSS score (1.39%). Track it; it rarely justifies an emergency change on its own.
Description
Mailvelope prior to 3.3.0 accepts or operates with invalid PGP public keys: Mailvelope allows importing keys that contain users without a valid self-certification. Keys that are obviously invalid are not rejected during import. An attacker that is able to get a victim to import a manipulated key could claim to have signed a message that originates from another person.
