High CVSS 7.5

CVE-2026-47840

NVD analysis in progress

A network attacker positioned between UAA and its LDAP directory can impersonate the directory using any certificate from any trusted CA, then harvest the LDAP bind password and every end-user password sent during simple-bind authentication, and return forged group memberships that grant themselves admin scopes. This affects every deployment that authenticates users against LDAP over StartTLS. Affected versions: UAA versions prior to v78.13.0; Cf-deployment versions prior to v56.2.0.

What this means

Exposure
Exploitable remotely over the network, without authentication and with no action from the victim. The attack does require particular conditions, which makes it less systematic.
Impact
An attacker can read some data and modify or destroy data. The impact spreads beyond the vulnerable component into other parts of the system.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle. Start with the instances exposed to the internet.
