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-2026-18825 in the wild and no public exploit code.\n\nAffected product: github.com/antono connect-cors. 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-2026-18825/ (Markdown: https://insights.sbomify.com/CVE-2026-18825/index.md)","id":"CVE-2026-18825","markdown":"https://insights.sbomify.com/CVE-2026-18825/index.md","name":"CVE-2026-18825","record":{"aliases":["GHSA-8f76-923c-xvfq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js CORS middleware","requires_auth":"none","summary":"Attackers can bypass origin verification in connect-xcors to perform cross-domain authenticated requests, requiring library upgrades.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TCS-CERT","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"An Origin Validation Error in the middleware of the connect-xcors npm package allows an attacker to bypass origin verification and perform a cross domain authenticated request.","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":"Origin validation error in the connect-xcors npm package","id":"CVE-2026-18825","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Vulnerabilities in IBM AIX and PowerVM VIOS","id":"CVE-2026-18828"},"packages":[],"prev":{"headline":"Vulnerabilities in IBM AIX and PowerVM VIOS","id":"CVE-2026-18824"},"products":["connect-cors"],"published":"2026-09-28","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":"2026-10-05","vendors":["github.com/antono"]},"summary":"Attackers can bypass origin verification in connect-xcors to perform cross-domain authenticated requests, requiring library upgrades.","url":"https://insights.sbomify.com/CVE-2026-18825/"}
