An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-58263 exists.\n\nAffected packages and fixed versions:\n- jodit (npm): affected all versions; fixed in 4.12.28\n- jodit (npm): affected all versions; fixed in 4.12.28\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-2026-58263/ (Markdown: https://insights.sbomify.com/CVE-2026-58263/index.md)","id":"CVE-2026-58263","markdown":"https://insights.sbomify.com/CVE-2026-58263/index.md","name":"CVE-2026-58263","record":{"aliases":["GHSA-rxcw-mc6f-6hr3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jodit Editor","requires_auth":"none","summary":"Attackers can bypass the HTML sanitizer to inject malicious scripts that execute automatically when the editor content is rendered.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-83","name":"Improper Neutralization of Script in Attributes in a Web Page"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Jodit Editor is a WYSIWYG editor with a built-in file browser \u0026 image editor. In versions prior to 4.12.28, the built-in clean-html sanitizer can be bypassed by a MathML/\u003cstyle\u003e carrier that hides a dangerous element from the sanitizer's element walk, so a no-interaction event handler survives into the editor value, potentially causing Mutation XSS. When an application supplies attacker-influenced HTML to the editor's value-set or insertion paths, the sanitized output still contains a live \u003cimg ... onload=...\u003e (or another non-onerror handler such as onfocus). A consumer that renders that output (element.innerHTML = editor.value) executes the handler with no user interaction.
