CVE-2024-38351Network attack vector

Account takeover via retained pre-linking password

Published Jun 18, 2024 · Updated Aug 2, 2024

Authentication bypass in PocketBase before 0.22.14 allows remote attackers to retain access to a victim account after OAuth2 linking. The OAuth2 autolinking flow associates a verified OAuth2 identity with an existing unverified email record without resetting that record's attacker-chosen password. Both password and OAuth2 authentication must be enabled, and the targeted user must complete OAuth2 sign-up with the same email before the attacker can log in as that user.
