GHSA-98JV-R7R8-3RQM

Vulnerability from github – Published: 2026-04-16 09:31 – Updated: 2026-04-16 09:31
VLAI
Details

The XML parsers within multiple WSO2 products accept user-supplied XML data without properly configuring to prevent the resolution of external entities. This omission allows malicious actors to craft XML payloads that exploit the parser's behavior, leading to the inclusion of 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.

Mitigation
Implementation System Configuration

Many XML parsers and validators can be configured to disable external entity expansion.

CAPEC-221: Data Serialization External Entities Blowup

This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
