An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-54661 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- swagger-typescript-api (npm): affected all versions; fixed in 13.12.2\n- swagger-typescript-api (npm): affected all versions; fixed in 13.12.2\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-2026-54661/ (Markdown: https://insights.sbomify.com/CVE-2026-54661/index.md)","id":"CVE-2026-54661","markdown":"https://insights.sbomify.com/CVE-2026-54661/index.md","name":"CVE-2026-54661","record":{"aliases":["GHSA-38c3-wv3c-v3xj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TypeScript API generator","requires_auth":"none","summary":"Attackers can inject code into generated Axios clients via malicious OpenAPI specs, leading to execution during client instantiation.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-1336","name":"Improper Neutralization of Special Elements Used in a Template Engine"}],"description":"swagger-typescript-api generates API clients for Fetch or Axios from an OpenAPI Specification.
