An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-15599 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- dompurify (npm): affected from 2.5.3 up to 2.5.8; no fix listed\n- dompurify (npm): affected from 2.5.3 up to 2.5.8; no fix listed\n- dompurify (npm): affected from 3.1.3; fixed in 3.2.7\n- dompurify (npm): affected from 3.1.3; fixed in 3.2.7\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-15599/ (Markdown: https://insights.sbomify.com/CVE-2025-15599/index.md)","id":"CVE-2025-15599","markdown":"https://insights.sbomify.com/CVE-2025-15599/index.md","name":"CVE-2025-15599","record":{"aliases":["CLEANSTART-2026-IS78920","CLEANSTART-2026-OE48815","DEBIAN-CVE-2025-15599","GHSA-v8jm-5vwx-cfxm","MINI-7m2x-wj4h-gqc9","MINI-jg9f-h574-fj9c","MINI-wp9q-vhpc-f58x","ROOT-APP-NPM-CVE-2025-15599","UBUNTU-CVE-2025-15599"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript sanitization library","requires_auth":"none","summary":"Attackers can execute JavaScript by bypassing DOMPurify's XML sanitization via textarea rawtext tags, affecting applications using the library.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"dompurify","vendor":"cure53"}],"cvss":{"score":5.1,"severity":"medium","source":"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","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"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.
