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-2026-0601 in the wild and no public exploit code.\n\nAffected product: Sonatype Nexus Repository. 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-2026-0601/ (Markdown: https://insights.sbomify.com/CVE-2026-0601/index.md)","id":"CVE-2026-0601","markdown":"https://insights.sbomify.com/CVE-2026-0601/index.md","name":"CVE-2026-0601","record":{"aliases":["GHSA-7j27-hv22-fqgw"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Nexus Repository","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary JavaScript in victims' browsers via reflected XSS in Nexus Repository 3, requiring user interaction.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Sonatype","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A reflected cross-site scripting vulnerability exists in Nexus Repository 3 that allows unauthenticated attackers to execute arbitrary JavaScript in a victim's browser through a specially crafted request requiring user interaction.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Nexus Repository 3 - Cross-Site Scripting","id":"CVE-2026-0601","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Authentication Bypass Using an Alternate Path or Channel in GitLab","id":"CVE-2026-0602"},"packages":[],"prev":{"headline":"Nexus Repository 3 - Server-Side Request Forgery in Proxy Repository Configuration","id":"CVE-2026-0600"},"products":["Nexus Repository"],"published":"2026-01-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-15","vendors":["Sonatype"]},"summary":"Unauthenticated attackers can execute arbitrary JavaScript in victims' browsers via reflected XSS in Nexus Repository 3, requiring user interaction.","url":"https://insights.sbomify.com/CVE-2026-0601/"}
