CVE-2023-22832
Flow configurations that include the ExtractCCDAAttributes Processor are vulnerable to malicious XML documents that contain Document Type Declarations with XML External Entity references.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Flow configurations that include the ExtractCCDAAttributes Processor are vulnerable to malicious XML documents that contain Document Type Declarations with XML External Entity references.
