Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-55131 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- node (Bitnami): affected all versions; fixed in 20.20.0, 22.22.0, 24.13.0, 25.3.0\n- node-min (Bitnami): affected all versions; fixed in 20.20.0, 22.22.0, 24.13.0, 25.3.0\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-2025-55131/ (Markdown: https://insights.sbomify.com/CVE-2025-55131/index.md)","id":"CVE-2025-55131","markdown":"https://insights.sbomify.com/CVE-2025-55131/index.md","name":"CVE-2025-55131","record":{"aliases":["ALPINE-CVE-2025-55131","AZL-74967","AZL-74979","BELL-CVE-2025-55131","BIT-node-2025-55131","BIT-node-min-2025-55131","CLEANSTART-2026-MI22504","DEBIAN-CVE-2025-55131","GHSA-9jwr-p39p-hwg2","MINI-23mf-fgc4-96h9","MINI-2879-25p2-fj5g","MINI-3747-89qx-52wg","MINI-3c7f-4rm2-rh2g","MINI-4hr2-g5c2-6ww2","MINI-cfv7-wwhr-p5gx","MINI-p8g3-72hc-7wr7","UBUNTU-CVE-2025-55131"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Node.js runtime","requires_auth":"low_privilege","summary":"Node.js buffer allocation flaw exposes uninitialized memory, potentially leaking secrets or corrupting data when using the vm module with timeouts.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L","version":"3.0"},"cwes":[{"id":"CWE-497","name":"Exposure of Sensitive System Information to an Unauthorized Control Sphere"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A flaw in Node.js's buffer allocation logic can expose uninitialized memory when allocations are interrupted, when using the `vm` module with the timeout option. Under specific timing conditions, buffers allocated with `Buffer.alloc` and other `TypedArray` instances like `Uint8Array` may contain leftover data from previous operations, allowing in-process secrets like tokens or passwords to leak or causing data corruption. While exploitation typically requires precise timing or in-process code execution, it can become remotely exploitable when untrusted input influences workload and timeouts, leading to potential confidentiality and integrity impact.","ecosystems":["Bitnami"],"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":"Information disclosure in node","id":"CVE-2025-55131","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"information_disclosure","year":"2025"},"n_packages":2,"n_references":1,"next":{"headline":"Missing authorization in node","id":"CVE-2025-55132"},"packages":[{"ecosystem":"Bitnami","fixed":["20.20.0","22.22.0","24.13.0","25.3.0"],"introduced":["0","21.0.0","23.0.0","25.0.0"],"last_affected":[],"package":"node","purl":"pkg:bitnami/node","source":"BIT-node-2025-55131"},{"ecosystem":"Bitnami","fixed":["20.20.0","22.22.0","24.13.0","25.3.0"],"introduced":["0","21.0.0","23.0.0","25.0.0"],"last_affected":[],"package":"node-min","purl":"pkg:bitnami/node-min","source":"BIT-node-min-2025-55131"}],"prev":{"headline":"Path traversal in node","id":"CVE-2025-55130"},"products":["node"],"published":"2026-01-20","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"total"},"state":"PUBLISHED","updated":"2026-07-15","vendors":["nodejs"]},"summary":"Node.js buffer allocation flaw exposes uninitialized memory, potentially leaking secrets or corrupting data when using the vm module with timeouts.","url":"https://insights.sbomify.com/CVE-2025-55131/"}
