Operationally, ranked in the top 1.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2022-30995 is a sensitive information disclosure vulnerability stemming from improper authentication, tracked under CWE-287. It affects Acronis Cyber Protect 15 on Windows and Linux prior to build 29486, as well as Acronis Cyber Backup 12.5 on Windows and Linux prior to build 16545. The flaw carries a CVSS 3.1 base score of 7.5 with a network attack vector, low complexity, and no required privileges or user interaction, resulting in high confidentiality impact.
An unauthenticated remote attacker can exploit the weakness over the network to access sensitive data stored or managed by the affected backup and protection products. Because the vulnerability requires no credentials, it can be triggered directly against exposed instances, potentially exposing configuration details, backup metadata, or other protected information without further interaction.
The vendor advisory at https://security-advisory.acronis.com/advisories/SEC-3855 identifies the fixed builds and directs administrators to apply the updates that resolve the authentication issue. The associated EPSS score has remained steady at 0.6252 with no material increase observed after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
