Very low probability of exploitation
EPSS predicts the probability of exploitation in the next 30 days based on real-world threat data, complementing CVSS severity scores with actual risk assessment.
OpenBao users with access to the sys/leases/revoke/:lease_id endpoint in any namespace can revoke leases in any other namespace as long as the lease identifier is known to them, bypassing ACLs that should apply for cross-namespace revocations.
OpenBao's namespaces provide multi-tenant separation. A tenant who intentionally leaks lease identifiers can have their lease and underlying credential revoked by a user in another tenant.
This will be fixed in OpenBao v2.5.5.
