This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An improper authorization vulnerability in fosrl/pangolin through v1.20.0 allows an authenticated remote attacker to authenticate to any resource in any organization by reusing an access token issued for a different resource. The server/routers/resource/authWithAccessToken.ts handler calls verifyResourceAccessToken() without passing the target resourceId, so a valid token scoped to resource X in organization A passes verification for resource Y in organization B.
