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.
