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-2026-84369 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- svgo (npm): affected from 1.0.0; fixed in 2.8.4\n- svgo (npm): affected from 1.0.0; fixed in 2.8.4\n- svgo (npm): affected from 3.0.0; fixed in 3.3.5\n- svgo (npm): affected from 3.0.0; fixed in 3.3.5\n- svgo (npm): affected from 4.0.0; fixed in 4.1.0\n- svgo (npm): affected from 4.0.0; fixed in 4.1.0\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-2026-84369/ (Markdown: https://insights.sbomify.com/CVE-2026-84369/index.md)","id":"CVE-2026-84369","markdown":"https://insights.sbomify.com/CVE-2026-84369/index.md","name":"CVE-2026-84369","record":{"aliases":["CLSA-2026-1790520171","DEBIAN-CVE-2026-84369","GHSA-4vpr-x523-8j87"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"SVG optimization library","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in victim browsers via unsanitized HTML in SVG foreignObject elements when using the opt-in removeScripts plugin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"SVGO, short for SVG Optimizer, is a Node.js library and command-line application for optimizing SVG files. From version 1.0.0 until versions 2.8.4, 3.3.5, and 4.1.0, the opt-in removeScripts plugin, named removeScriptElement in versions 2 and 3 and implemented in plugins/removeScripts.js, removes SVG and XHTML script elements but does not inspect executable HTML content inside SVG foreignObject elements. Event-handler attributes such as onload and onbeforetoggle, srcdoc documents, and executable URLs in the action, data, formaction, href, and src attributes can remain in attacker-controlled SVG input. When an application uses the plugin as its only protection and serves the optimized SVG in an active browser context, the payload can execute script in the viewer's origin, expose data, modify content, or perform actions as the victim. This issue is fixed in versions 2.8.4, 3.3.5, and 4.1.0.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"SVGO: removeScripts incompletely sanitizes executable HTML in SVG foreignObject elements","id":"CVE-2026-84369","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":6,"n_references":10,"next":{"headline":"SVGO: removeScripts allows executable links through namespace and control-character bypasses","id":"CVE-2026-84370"},"packages":[{"ecosystem":"npm","fixed":["2.8.4"],"introduced":["1.0.0"],"last_affected":[],"package":"svgo","purl":null,"source":"GHSA-4vpr-x523-8j87"},{"ecosystem":"npm","fixed":["2.8.4"],"introduced":["1.0.0"],"last_affected":[],"package":"svgo","purl":"pkg:npm/svgo","source":"GHSA-4vpr-x523-8j87"},{"ecosystem":"npm","fixed":["3.3.5"],"introduced":["3.0.0"],"last_affected":[],"package":"svgo","purl":null,"source":"GHSA-4vpr-x523-8j87"},{"ecosystem":"npm","fixed":["3.3.5"],"introduced":["3.0.0"],"last_affected":[],"package":"svgo","purl":"pkg:npm/svgo","source":"GHSA-4vpr-x523-8j87"},{"ecosystem":"npm","fixed":["4.1.0"],"introduced":["4.0.0"],"last_affected":[],"package":"svgo","purl":null,"source":"GHSA-4vpr-x523-8j87"},{"ecosystem":"npm","fixed":["4.1.0"],"introduced":["4.0.0"],"last_affected":[],"package":"svgo","purl":"pkg:npm/svgo","source":"GHSA-4vpr-x523-8j87"}],"prev":{"headline":"joi: Prototype pollution via a `__proto__` language key in custom messages","id":"CVE-2026-84368"},"products":["svgo"],"published":"2026-09-01","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-02","vendors":["svg"]},"summary":"Attackers can execute arbitrary JavaScript in victim browsers via unsanitized HTML in SVG foreignObject elements when using the opt-in removeScripts plugin.","url":"https://insights.sbomify.com/CVE-2026-84369/"}
