CVE-2026-23782
Published: 10 April 2026
Summary
CVE-2026-23782 is a high-severity Improper Access Control (CWE-284) vulnerability in Bmc Control-M\/Managed File Transfer. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 26.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement).
Deeper analysis
CVE-2026-23782 is a vulnerability discovered in BMC Control-M/MFT versions 9.0.20 through 9.0.22. The issue resides in an API management endpoint that permits unauthenticated users to retrieve both an API identifier and its corresponding secret value, exposing sensitive credentials that should remain protected.
Unauthenticated remote attackers can exploit this vulnerability with low complexity, requiring no privileges or user interaction, as indicated by its CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). By obtaining the exposed API secrets, attackers can invoke privileged API operations, potentially resulting in unauthorized access to the system.
BMC advisories detail mitigation through available patches, such as the Control-M Server patch PACTV-9-0-21-308, accessible at https://docs.bmc.com/xwiki/bin/view/Control-M-Orchestration/Control-M/ctm9021/Patches/Control-M-Server-PACTV-9-0-21-308/?srid=ab0apVT3.

Why these techniques?
Vulnerability in public API endpoint enables unauthenticated credential disclosure (T1552) and direct exploitation of exposed public-facing application (T1190) to obtain valid API secrets for privileged access.

AC-14 requires organizations to explicitly limit and document permitted actions without authentication, directly preventing unauthenticated access to sensitive API secrets via management endpoints.
AC-3 enforces approved authorizations for access to system resources, mitigating the vulnerability by ensuring the API endpoint requires authentication before disclosing secrets.
IA-5 mandates protection of authenticators like API secrets from unauthorized disclosure, addressing the exposure of credentials that enable privileged operations.
