An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-101902 exists.\n\nAffected packages and fixed versions:\n- axios (npm): affected from 0.27.2; fixed in 0.34.0\n- axios (npm): affected from 0.27.2; fixed in 0.34.0\n- axios (npm): affected from 1.0.0; fixed in 1.20.0\n- axios (npm): affected from 1.0.0; fixed in 1.20.0\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-2026-101902/ (Markdown: https://insights.sbomify.com/CVE-2026-101902/index.md)","id":"CVE-2026-101902","markdown":"https://insights.sbomify.com/CVE-2026-101902/index.md","name":"CVE-2026-101902","record":{"aliases":["AZL-105245","CLEANSTART-2026-CB38502","CLEANSTART-2026-YP57972","DEBIAN-CVE-2026-101902","ECHO-6bca-9fdf-e5cd","GHSA-9fr6-4gfg-395g","MINI-323c-fgh3-vx4q","MINI-3p94-qq55-5p46","MINI-4wfx-4gpq-9hff","MINI-559h-p6f4-c3p2","MINI-7fvc-m464-rw2q","MINI-7q6r-8ph3-r2px","MINI-cjhp-rp39-r3vc","MINI-cq32-wpqp-w7x7","MINI-hh94-8fc9-gqxf","MINI-hhrc-9c4c-j4g7","MINI-j9h8-cg8g-6924","MINI-jj26-mfcx-gff6","MINI-jxf3-5fj8-x65w","MINI-m3hh-h7fj-93jp","MINI-m8cv-f59v-wp33","MINI-qrrw-383j-6879","MINI-rqm8-5wgp-276m","MINI-wjf4-593g-7rg5","UBUNTU-CVE-2026-101902"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript HTTP client","requires_auth":"none","summary":"Prototype pollution gadget in Axios allows attackers to override HTTP methods if Object.prototype is polluted, potentially causing unintended state-changing requests.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","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:N/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 0.27.2 until 0.34.0 and 1.20.0, Axios default-instance requests that omit an explicit method can read an inherited method value from Object.prototype. If another vulnerability in the same process pollutes Object.prototype.method, calls such as axios.request({ url }) and axios({ url }) can send a state-changing HTTP method instead of the expected default GET. Axios does not create the prototype pollution source. This is a read-side gadget in axios request dispatch.
