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-2018-18553 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2018-18553/ (Markdown: https://insights.sbomify.com/CVE-2018-18553/index.md)","id":"CVE-2018-18553","markdown":"https://insights.sbomify.com/CVE-2018-18553/index.md","name":"CVE-2018-18553","record":{"aliases":["GHSA-h839-88jf-jx3g"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Leanote note-taking app","requires_auth":"none","summary":"Attackers can inject malicious scripts via the blog title field, leading to cross-site scripting attacks on the likes page.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"leanote","vendor":"leanote"}],"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":"Leanote 2.6.1 has XSS via the Blog Basic Setting title field, which is mishandled during rendering of the \"likes\" page.","ecosystems":[],"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 n/a","id":"CVE-2018-18553","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in n/a","id":"CVE-2018-18555"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2018-18552"},"products":["n/a"],"published":"2018-10-22","related":[{"cvss_score":9.6,"headline":"Cross-site scripting in n/a","id":"CVE-2020-26157","kev_date_added":null,"published":"2020-09-30"},{"cvss_score":9.6,"headline":"Cross-site scripting in n/a","id":"CVE-2020-26158","kev_date_added":null,"published":"2020-09-30"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2021-43721","kev_date_added":null,"published":"2022-03-28"},{"cvss_score":6.1,"headline":"Cross-site scripting in Leanote","id":"CVE-2019-1010003","kev_date_added":null,"published":"2019-07-11"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2017-1000459","kev_date_added":null,"published":"2018-01-03"},{"cvss_score":3.5,"headline":"leanote history.js define cross site scripting","id":"CVE-2021-4263","kev_date_added":null,"published":"2022-12-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"Attackers can inject malicious scripts via the blog title field, leading to cross-site scripting attacks on the likes page.","url":"https://insights.sbomify.com/CVE-2018-18553/"}
