Summary
CVE-2024-2374 is a high-severity Improper Restriction of XML External Entity Reference (CWE-611) vulnerability in Wso2 Api Manager. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 30th 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.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-2374 is an XML External Entity (XXE) vulnerability, classified under CWE-611, affecting the XML parsers in multiple WSO2 products. These parsers accept user-supplied XML data without proper configuration to prevent the resolution of external entities. Published on 2026-04-16, the flaw has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact with network accessibility, low attack complexity, and no privileges required.
Remote attackers without authentication can exploit this vulnerability by crafting malicious XML payloads submitted to the affected products. Successful exploitation enables reading confidential files from the server's file system, accessing limited HTTP resources reachable by the product, or conducting denial-of-service attacks through recursive entity expansion or fetching large external resources, thereby exhausting server resources.
For mitigation details, refer to the WSO2 security advisory at https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2026/WSO2-2024-3255/.

external resources. By leveraging this vulnerability, an attacker can read confidential files from the file system and access limited HTTP resources reachable by the product. Additionally, the vulnerability can be exploited to perform denial of service attacks by exhausting server resources through recursive entity expansion or fetching large external resources.

Vulnerability scanning can discover XXE flaws but does not prevent their introduction in code.
Hardened XML parser configurations directly disable external entity resolution.
Patching eliminates XXE-vulnerable parser versions but is only one aspect of software maintenance.
Secure SDLC practices include input validation and safe XML parser configuration that prevent XXE.
