CVE-2026-108547
AstronRPA through 1.1.6 contains a missing tenant authorization check in robot-service that allows authenticated users to read other tenants' shared variables via the get-batch-shared-var endpoint.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
AstronRPA through 1.1.6 contains a missing tenant authorization check in robot-service that allows authenticated users to read other tenants' shared variables via the get-batch-shared-var endpoint. Attackers can enumerate sequential shared variable IDs and decrypt all-users variables re-encrypted with their own tenant key to recover other tenants' credentials in plaintext.
