CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:LSummary
CVE-2025-36247 is a high-severity Improper Restriction of XML External Entity Reference (CWE-611) vulnerability in Ibm Db2. Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and SA-11 (Developer Testing and Evaluation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-36247 is an XML external entity injection (XXE) vulnerability, classified under CWE-611, 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 occurs when the software processes XML data, potentially allowing injection of malicious external entities.
A remote attacker with low privileges can exploit this vulnerability over the network with low attack complexity and no user interaction required. Exploitation enables disclosure of sensitive information due to high confidentiality impact or consumption of memory resources resulting in limited availability impact, consistent with the CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L).
