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-2026-18329 in the wild and no public exploit code.\n\nAffected product: F5 NGINX JavaScript. 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-2026-18329/ (Markdown: https://insights.sbomify.com/CVE-2026-18329/index.md)","id":"CVE-2026-18329","markdown":"https://insights.sbomify.com/CVE-2026-18329/index.md","name":"CVE-2026-18329","record":{"aliases":["AZL-99303","DEBIAN-CVE-2026-18329","GHSA-jm9r-m8jm-j2hr","UBUNTU-CVE-2026-18329"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"NGINX JavaScript module","requires_auth":"none","summary":"An unauthenticated attacker can bypass js_access controls by triggering an exception during asynchronous body processing, gaining unauthorized access to protected resources.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-636","name":"Not Failing Securely"}],"description":"Description\n\nNGINX JavaScript (njs) and QuickJS (qjs) engines have a vulnerability when a js_access handler performs asynchronous request body processing and an exception is thrown during asynchronous access-control evaluation before an explicit access denial is returned. An unauthenticated attacker can exploit this vulnerability by sending a crafted HTTP request that triggers an error condition in the access validation logic. This may cause the js_access phase to fail open, allowing the request to proceed instead of being denied, resulting in an authentication or authorization bypass and unauthorized access to protected resources.\n\nImpact\n\nThis vulnerability may allow remote attackers to bypass js_access controls. There is no control plane exposure; this is a data plane issue only.\n\nNote: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"NGINX ngx_http_js_module vulnerability","id":"CVE-2026-18329","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Hardcoded Shared RSA-1024 Private Key in Web Login in TP-Link RE305 and Archer C7","id":"CVE-2026-18330"},"packages":[],"prev":{"headline":"Forminator Forms \u003c= 1.57.0 - Unauthenticated DOM-Based Cross-Site Scripting via 'error_description' Parameter","id":"CVE-2026-18328"},"products":["NGINX JavaScript"],"published":"2026-09-02","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-02","vendors":["F5"]},"summary":"An unauthenticated attacker can bypass js_access controls by triggering an exception during asynchronous body processing, gaining unauthorized access to protected resources.","url":"https://insights.sbomify.com/CVE-2026-18329/"}
