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-2026-101908/ (Markdown: https://insights.sbomify.com/CVE-2026-101908/index.md)","id":"CVE-2026-101908","markdown":"https://insights.sbomify.com/CVE-2026-101908/index.md","name":"CVE-2026-101908","record":{"aliases":["CLEANSTART-2026-EI20913","CLEANSTART-2026-MZ38704","CLEANSTART-2026-VK76913","CLEANSTART-2026-ZN41930","DEBIAN-CVE-2026-101908","ECHO-3007-50ef-28a9","GHSA-vh66-26gq-q6x8","MINI-2r4f-pp9j-48m6","MINI-3348-5gmh-pr4h","MINI-4c3r-q59q-m2j2","MINI-5p9g-h4m5-4vrf","MINI-7c2h-fg2q-ff2v","MINI-89xv-287m-jrfg","MINI-c8cv-2xq5-jvw8","MINI-fhgc-q3pf-68jc","MINI-gx98-j7mq-f69f","MINI-hpvh-23vg-mw8h","MINI-jmc3-3mh3-7jpf","MINI-p676-584f-8mjv","MINI-phjv-427h-qh62","MINI-q9x3-8hwr-x3h8","MINI-r3r9-6r4m-q88g","MINI-x8rc-qq2f-hgxf","MINI-xh5m-xx3w-g875","MINI-xj3m-p7v8-394r","UBUNTU-CVE-2026-101908"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"Axios is a promise-based HTTP client for the browser and Node.js. From 1.7.0 until 1.20.0, the fetch adapter constructs a Request with sanitized resolvedOptions but then calls fetch with the original fetchOptions. A separate same-process prototype-pollution flaw populates Object.prototype.headers so fetchOptions.headers resolves through inheritance. The inherited fetchOptions.headers value overrides the sanitized Request headers through the second argument to fetch after Request construction. Attacker-controlled request headers can alter authorization, caching, metadata-service access, or application-specific behavior.
