Likely Mitigating ControlsAI

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.

AC-24 Access Control Decisions
addresses: CWE-639

Per-request decision making makes it harder to bypass authorization using user-controlled keys without proper validation in the decision process.

AC-3 Access Enforcement
addresses: CWE-639

Consistent enforcement of approved authorizations makes bypassing via user-controlled keys ineffective.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Deeper analysisAI

CVE-2025-36365 is an authorization bypass vulnerability (CWE-639) affecting IBM Db2 for Linux, UNIX, and Windows, including Db2 Connect Server, in versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.3. The issue arises under specific configurations of cataloged remote storage aliases, where an authenticated user can execute unauthorized commands by using a user-controlled key. It was published on 2026-01-30 with a CVSS v3.1 base score of 6.8 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N).

An authenticated user with low privileges (PR:L) can exploit this vulnerability over the network (AV:N), though it requires high attack complexity (AC:H) and no user interaction (UI:N). Successful exploitation results in high impacts to confidentiality and integrity (C:H/I:H) with no availability impact (A:N), allowing the execution of unauthorized commands.
