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.","state":0,"publishedAt":"2025-10-17T05:15:33.96+00:00","modifiedAt":"2026-10-19T16:10:00.26+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · report@snyk.io · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:N/SA:H/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":5.4,"severity":"MEDIUM"},{"system":"CVSS 3.1 · report@snyk.io · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:H","score":9.3,"severity":"CRITICAL"}],"references":["https://gist.github.com/AudunWA/4d690d9ae5efdafe7cf71d9c2ee90a10","https://github.com/mwilliamson/mammoth.js/commit/c54aaeb43a7941317c1f3c119ffa92090f988820","https://security.snyk.io/vuln/SNYK-DOTNET-MAMMOTH-13561968","https://security.snyk.io/vuln/SNYK-JAVA-ORGZWOBBLEMAMMOTH-13561969","https://security.snyk.io/vuln/SNYK-JS-MAMMOTH-13554470","https://security.snyk.io/vuln/SNYK-PYTHON-MAMMOTH-13561967"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-11849","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-22"],"productCriteria":[],"sourceDates":{"published":"2025-10-17T05:15:33.960","lastModified":"2026-10-19T16:10:00.260"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
