CVE-2020-11061 is a high-severity vulnerability rated 7.4/10 on the CVSS scale. In Bareos Director less than or equal to 16.2.10, 17.2.9, 18.2.8, and 19.2.7, a heap overflow allows a malicious client to corrupt the director's memory via oversized digest strings sent during initialization of a verify job. Disabling verify jobs mitigates the problem. EPSS estimates a 1.24% chance of exploitation in the next 30 days.
