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-2022-21802 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- grapesjs (npm): affected all versions; no fix listed\n- grapesjs (npm): affected all versions; 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-2022-21802/ (Markdown: https://insights.sbomify.com/CVE-2022-21802/index.md)","id":"CVE-2022-21802","markdown":"https://insights.sbomify.com/CVE-2022-21802/index.md","name":"CVE-2022-21802","record":{"aliases":["GHSA-589f-c66p-hxr4"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript library","requires_auth":"none","summary":"An attacker can execute arbitrary scripts via improper sanitization of class names in the Selector Manager of the GrapesJS library.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"grapesjs","vendor":"grapesjs"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N/E:P","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The package grapesjs before 0.19.5 are vulnerable to Cross-site Scripting (XSS) due to an improper sanitization of the class name in Selector Manager.","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":false,"headline":"Cross-site Scripting (XSS)","id":"CVE-2022-21802","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2022"},"n_packages":2,"n_references":5,"next":{"headline":"Prototype Pollution","id":"CVE-2022-21803"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"grapesjs","purl":null,"source":"GHSA-589f-c66p-hxr4"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"grapesjs","purl":"pkg:npm/grapesjs","source":"GHSA-589f-c66p-hxr4"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2022-21801"},"products":["grapesjs"],"published":"2022-07-25","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":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["n/a"]},"summary":"An attacker can execute arbitrary scripts via improper sanitization of class names in the Selector Manager of the GrapesJS library.","url":"https://insights.sbomify.com/CVE-2022-21802/"}
