# CVE-2025-15599: DOMPurify XSS via Textarea Rawtext Bypass in SAFE\_FOR\_XML

- Also known as: GHSA-V8JM-5VWX-CFXM
- Severity: CVSS 5.1 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 3.2.7
- Published: 2026-03-03 · Updated: 2026-10-08

## Affected

- cure53 DOMPurify: from 3.1.3, through 3.2.6; from 2.5.3, through 2.5.8
- dompurify (npm): from 3.1.3, fixed in 3.2.7
- dompurify (npm): from 2.5.3, through 2.5.8

## Description

DOMPurify 3.1.3 through 3.2.6 and 2.5.3 through 2.5.8 contain a cross-site scripting vulnerability that allows attackers to bypass attribute sanitization by exploiting missing textarea rawtext element validation in the SAFE_FOR_XML regex. Attackers can include closing rawtext tags like </textarea> in attribute values to break out of rawtext contexts and execute JavaScript when sanitized output is placed inside rawtext elements. The 3.x branch was fixed in 3.2.7; the 2.x branch was never patched.
