Any signed-in user can exploit it over the network, 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-2024-27932 exists.\n\nAffected packages and fixed versions:\n- deno (crates.io): affected from 1.8.0; fixed in 1.40.4\n- deno (crates.io): affected from 1.8.0; fixed in 1.40.4\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-2024-27932/ (Markdown: https://insights.sbomify.com/CVE-2024-27932/index.md)","id":"CVE-2024-27932","markdown":"https://insights.sbomify.com/CVE-2024-27932/index.md","name":"CVE-2024-27932","record":{"aliases":["GHSA-5frw-4rwq-xhcr","JLSEC-2026-104"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Deno runtime","requires_auth":"low_privilege","summary":"Improper hostname matching in Deno's auth token handling may leak tokens to unintended domains when importing untrusted code.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"deno","vendor":"deno"}],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Deno is a JavaScript, TypeScript, and WebAssembly runtime.
