An attacker can exploit it over the internet without logging in, 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-2026-48995 exists.\n\nAffected packages and fixed versions:\n- pnpm (npm): affected all versions; fixed in 10.33.4\n- pnpm (npm): affected all versions; fixed in 10.33.4\n- pnpm (npm): affected from 11.0.0; fixed in 11.0.7\n- pnpm (npm): affected from 11.0.0; fixed in 11.0.7\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-2026-48995/ (Markdown: https://insights.sbomify.com/CVE-2026-48995/index.md)","id":"CVE-2026-48995","markdown":"https://insights.sbomify.com/CVE-2026-48995/index.md","name":"CVE-2026-48995","record":{"aliases":["GHSA-hg3w-7f8c-63hp","MINI-r2r2-m3v2-84hm","ROOT-APP-NPM-CVE-2026-48995"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"pnpm package manager","requires_auth":"none","summary":"A compromised GitHub codeload server can serve malicious tarballs for git dependencies because pnpm does not verify their hashes against the lockfile.","user_interaction":"required","vuln_class":"supply_chain"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"pnpm","vendor":"pnpm"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U","version":"4.0"},"cwes":[{"id":"CWE-353","name":"Missing Support for Integrity Check"}],"description":"pnpm is a package manager.
