Technical Summary
CVE-2026-16138 affects In Progress ShareFile Storage Zones Controller version 5.12.5 and earlier. The vulnerability arises from unsafe deserialization of untrusted file metadata, which can be exploited by a user with write access to a network share to execute arbitrary code on the Storage Zones Controller host. This vulnerability is classified under CWE-502 (Deserialization of Untrusted Data) and has a CVSS v3.1 base score of 8.0, indicating high severity. There is no information about available patches or vendor advisories at this time.
Potential Impact
Successful exploitation allows an attacker with write access to a network share to execute arbitrary code on the Storage Zones Controller host, potentially leading to full compromise of the affected system. This impacts confidentiality, integrity, and availability of the system as indicated by the CVSS vector (C:H/I:H/A:H).
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict write access to network shares used by the Storage Zones Controller to trusted users only and monitor for suspicious activity related to file metadata processing.
