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-2018-19057 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- simplemde (npm): affected all versions up to 1.11.2; no fix listed\n- simplemde (npm): affected all versions up to 1.11.2; 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-2018-19057/ (Markdown: https://insights.sbomify.com/CVE-2018-19057/index.md)","id":"CVE-2018-19057","markdown":"https://insights.sbomify.com/CVE-2018-19057/index.md","name":"CVE-2018-19057","record":{"aliases":["GHSA-wg85-p6j7-gp3w"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Markdown editor library","requires_auth":"none","summary":"An attacker can execute arbitrary scripts in the victim's browser by crafting malicious Markdown input in the SimpleMDE editor.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"simplemde","vendor":"sparksuite"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"SimpleMDE 1.11.2 has XSS via an onerror attribute of a crafted IMG element, or via certain input with [ and ( characters, which is mishandled during construction of an A element.","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":"SimpleMDE XSS Vulnerability","id":"CVE-2018-19057","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2018"},"n_packages":2,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2018-19058"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.11.2"],"package":"simplemde","purl":null,"source":"GHSA-wg85-p6j7-gp3w"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.11.2"],"package":"simplemde","purl":"pkg:npm/simplemde","source":"GHSA-wg85-p6j7-gp3w"}],"prev":{"headline":"Pandao editor.md vulnerable to DOM XSS","id":"CVE-2018-19056"},"products":["n/a"],"published":"2018-11-07","related":[{"cvss_score":4.3,"headline":"Sparksuite SimpleMDE iFrame cross site scripting","id":"CVE-2024-0647","kev_date_added":null,"published":"2024-01-17"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"An attacker can execute arbitrary scripts in the victim's browser by crafting malicious Markdown input in the SimpleMDE editor.","url":"https://insights.sbomify.com/CVE-2018-19057/"}
