An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-23769 in the wild and no public exploit code.\n\nAffected product: NAVER lucy-xss-filter. 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-2026-23769/ (Markdown: https://insights.sbomify.com/CVE-2026-23769/index.md)","id":"CVE-2026-23769","markdown":"https://insights.sbomify.com/CVE-2026-23769/index.md","name":"CVE-2026-23769","record":{"aliases":["GHSA-vv6w-5g5j-5p4w"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Java XSS filter library","requires_auth":"none","summary":"Attackers can execute malicious JavaScript via improper sanitization in the lucy-xss-filter library when default superset rules are misconfigured.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"naver","cpe":[{"product":"lucy-xss-filter","vendor":"naver"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"lucy-xss-filter before commit e5826c0 allows an attacker to execute malicious JavaScript due to improper sanitization caused by misconfigured default superset rule files.","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 lucy-xss-filter","id":"CVE-2026-23769","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege escalation in Storage Manager","id":"CVE-2026-23772"},"packages":[],"prev":{"headline":"Server-side request forgery in lucy-xss-filter","id":"CVE-2026-23768"},"products":["lucy-xss-filter"],"published":"2026-01-16","related":[{"cvss_score":6.1,"headline":"Server-side request forgery in lucy-xss-filter","id":"CVE-2026-23768","kev_date_added":null,"published":"2026-01-16"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-16","vendors":["NAVER"]},"summary":"Attackers can execute malicious JavaScript via improper sanitization in the lucy-xss-filter library when default superset rules are misconfigured.","url":"https://insights.sbomify.com/CVE-2026-23769/"}
