An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-9266 exists.\n\nAffected packages and fixed versions:\n- express (npm): affected from 3.4.5; fixed in 4.0.0-rc1\n- express (npm): affected from 3.4.5; fixed in 4.0.0-rc1\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-2024-9266/ (Markdown: https://insights.sbomify.com/CVE-2024-9266/index.md)","id":"CVE-2024-9266","markdown":"https://insights.sbomify.com/CVE-2024-9266/index.md","name":"CVE-2024-9266","record":{"aliases":["GHSA-jj78-5fmv-mv28"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js web framework","requires_auth":"none","summary":"An open redirect vulnerability in the Express Response object allows attackers to redirect users to untrusted sites, potentially facilitating phishing attacks.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HeroDevs","cpe":[],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"URL Redirection to Untrusted Site ('Open Redirect') vulnerability in Express.
