GHSA-rmjr-87wv-gf87 Mammoth is vulnerable to Directory Traversal

• npm mammoth: >= 0.3.25, < 1.11.0 → fixed in 1.11.0 • Maven org.zwobble.mammoth:mammoth: < 1.11.0 → fixed in 1.11.0 • PyPI mammoth: >= 0.3.25, < 1.11.0 → fixed in 1.11.0 • NuGet Mammoth: < 1.11.0 → fixed in 1.11.0

Versions of the package mammoth from 0.3.25 and before 1.11.0; versions of the package mammoth from 0.3.25 and before 1.11.0; versions of the package mammoth before 1.11.0; versions of the package org.zwobble.mammoth:mammoth before 1.11.0 are vulnerable to Directory Traversal due to the lack of path or file type validation when processing a docx file containing an image with an external link (r:link attribute instead of embedded r:embed). The library resolves the URI to a file path and after reading, the content is encoded as base64 and included in the HTML output as a data URI. An attacker can read arbitrary files on the system where the conversion is performed or cause an excessive resources consumption by crafting a docx file that links to special device files such as /dev/random or /dev/zero.
