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-2021-30109 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- froala-editor (npm): affected all versions up to 3.2.6; no fix listed\n- froala-editor (npm): affected all versions up to 3.2.6; no fix listed\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-2021-30109/ (Markdown: https://insights.sbomify.com/CVE-2021-30109/index.md)","id":"CVE-2021-30109","markdown":"https://insights.sbomify.com/CVE-2021-30109/index.md","name":"CVE-2021-30109","record":{"aliases":["GHSA-cq6w-w5rj-p9x8"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Froala Editor","requires_auth":"none","summary":"Attackers can inject malicious scripts via crafted base64 strings in the hyperlink module, potentially executing code in user browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"froala_editor","vendor":"froala"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","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":"Froala Editor 3.2.6 is affected by Cross Site Scripting (XSS).
