CVE-2026-47840: Cloudfoundry Foundation Cf-Deployment

High severity, CVSS 7.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Cloudfoundry Foundation Cf-Deployment: before 56.2.0 (fixed in 56.2.0)
• Cloudfoundry Foundation Uaa: before 78.13.0 (fixed in 78.13.0)
