OSV		ECHO-B87A-6495-4598 Flagged by review on PR #19827: this ID needs a documented disposition here, not silent removal, since the raw scanner (matching on [email protected]'s version string alone) will otherwise keep reporting it as an open finding forever. Upstream's fix (GHSA-gvgg-2r3r-53x7) closes a path where OrganizationMemberResource trusted a client-session note to determine organization membership, letting a crafted note forge an org claim. 25.0.6's OrganizationMembershipMapper does not have that trust path at all — it always re-verifies membership directly against the organization store (provider.getByMember(user)) rather than trusting anything client- or session-supplied. With no client-session-note-based membership check present, the described forgery has no mechanism to exploit here.
