An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-42018 in the wild since at least 11 Sep 2026.\n\nAffected product: Jfrog Artifactory. 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-2026-42018/ (Markdown: https://insights.sbomify.com/CVE-2026-42018/index.md)","id":"CVE-2026-42018","markdown":"https://insights.sbomify.com/CVE-2026-42018/index.md","name":"CVE-2026-42018","record":{"aliases":["GHSA-3q94-gprh-7pwm"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"JFrog Artifactory","requires_auth":"none","summary":"Unauthenticated attackers can obtain internal anonymous tokens to access sensitive resources, even when anonymous access is disabled.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JFROG","cpe":[{"product":"artifactory","vendor":"jfrog"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"JFrog Artifactory could return an internal anonymous-user token to an unauthenticated caller when anonymous access is disabled, potentially exposing sensitive resources.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-42018.yaml","stars":null,"title":"JFrog Artifactory - Anonymous Token Disclosure via Trailing Slash Auth Bypass"}],"tier":"exploited"},"has_fix":null,"headline":"JFrog Artifactory Improper Authentication","id":"CVE-2026-42018","indexable":true,"kev":{"dateAdded":"2026-09-11","dueDate":"2026-09-25","knownRansomwareCampaignUse":"Unknown","product":"Artifactory","requiredAction":"Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes).
