Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-20903 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @atlaskit/editor-core (npm): affected all versions; no fix listed\n- @atlaskit/editor-core (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-2019-20903/ (Markdown: https://insights.sbomify.com/CVE-2019-20903/index.md)","id":"CVE-2019-20903","markdown":"https://insights.sbomify.com/CVE-2019-20903/index.md","name":"CVE-2019-20903","record":{"aliases":["GHSA-p5ch-w78f-xh44"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Atlassian editor library","requires_auth":"low_privilege","summary":"Remote attackers can inject arbitrary HTML or JavaScript via link targets in the Atlassian editor library, potentially executing code in user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"editor-core","vendor":"atlassian"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"The hyperlinks functionality in atlaskit/editor-core in before version 113.1.5 allows remote attackers to inject arbitrary HTML or JavaScript via a Cross-Site Scripting (XSS) vulnerability in link targets.","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 in @atlaskit/editor-core","id":"CVE-2019-20903","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2019"},"n_packages":2,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2019-20907"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"@atlaskit/editor-core","purl":null,"source":"GHSA-p5ch-w78f-xh44"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"@atlaskit/editor-core","purl":"pkg:npm/%40atlaskit/editor-core","source":"GHSA-p5ch-w78f-xh44"}],"prev":{"headline":"Business logic in Crowd","id":"CVE-2019-20902"},"products":["@atlaskit/editor-core"],"published":"2020-10-01","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":"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":"2024-09-17","vendors":["Atlassian"]},"summary":"Remote attackers can inject arbitrary HTML or JavaScript via link targets in the Atlassian editor library, potentially executing code in user sessions.","url":"https://insights.sbomify.com/CVE-2019-20903/"}
