DFN-CERT reported [1] a vulnerability in the OCSP feature in FreeRADIUS 2.1.11 where it does not verify the status of a certificate (e.g. if the certificate was revoked).

No further details, or a patch, were provided. According to the changelog on the FreeRADIUS site [2], OCSP support was added in version 2.1.11:

OCSP support from Alex Bergmann. See raddb/eap.conf, "ocsp" section.

Therefore earlier versions of FreeRADIUS are not affected by this flaw.
