CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:L

Exploitability: 1.4 / Impact: 3.7

Source: MITRE (Secondary)

Description

In xinclude in libxml2 before 2.15.4, xmlXIncludeProcess and xmlXIncludeProcessTree do not propagate parseFlags. This has security relevance for, for example, the XML_PARSE_NONET flag, if (without it) a custom resource loader accesses the internet and triggers XML external entity injection, SSRF, or a denial of service (e.g., for an attacker-controlled internet resource that is intentionally slow).
