An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-7301 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- sglang (PyPI): affected from 0.5.5 up to 0.5.12; no fix listed\n- sglang (PyPI): affected from 0.5.5 up to 0.5.12; no fix listed\n- sglang (PyPI): affected from 0.5.5 up to 0.5.12; no fix listed\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-2026-7301/ (Markdown: https://insights.sbomify.com/CVE-2026-7301/index.md)","id":"CVE-2026-7301","markdown":"https://insights.sbomify.com/CVE-2026-7301/index.md","name":"CVE-2026-7301","record":{"aliases":["GHSA-gwv6-pq6m-p3rq","PYSEC-2026-536"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SGLang runtime scheduler","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via pickle deserialization in the SGLang multimodal generation runtime scheduler's default network configuration.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"sglang","vendor":"lmsys"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"SGLangs multimodal generation runtime scheduler's ROUTER socket binds to 0.0.0.0 by default and contains a sink that calls pickle.loads() on incoming messages, enabling RCE when exposed to the internet.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"CVE-2026-7301","id":"CVE-2026-7301","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"CVE-2026-7302","id":"CVE-2026-7302"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0.5.5"],"last_affected":["0.5.12"],"package":"sglang","purl":null,"source":"GHSA-gwv6-pq6m-p3rq"},{"ecosystem":"PyPI","fixed":[],"introduced":["0.5.5"],"last_affected":["0.5.12"],"package":"sglang","purl":"pkg:pypi/sglang","source":"GHSA-gwv6-pq6m-p3rq"},{"ecosystem":"PyPI","fixed":[],"introduced":["0.5.5"],"last_affected":["0.5.12"],"package":"sglang","purl":"pkg:pypi/sglang","source":"PYSEC-2026-536"}],"prev":{"headline":"Memory corruption in Connext Professional","id":"CVE-2026-7300"},"products":["SGLang"],"published":"2026-05-18","related":[{"cvss_score":9.8,"headline":"CVE-2026-15969","id":"CVE-2026-15969","kev_date_added":null,"published":"2026-07-30"},{"cvss_score":9.8,"headline":"CVE-2026-15971","id":"CVE-2026-15971","kev_date_added":null,"published":"2026-07-30"},{"cvss_score":9.8,"headline":"CVE-2026-15976","id":"CVE-2026-15976","kev_date_added":null,"published":"2026-07-30"},{"cvss_score":9.8,"headline":"CVE-2026-7304","id":"CVE-2026-7304","kev_date_added":null,"published":"2026-05-18"},{"cvss_score":9.8,"headline":"CVE-2026-5760","id":"CVE-2026-5760","kev_date_added":null,"published":"2026-04-20"},{"cvss_score":9.8,"headline":"CVE-2026-3059","id":"CVE-2026-3059","kev_date_added":null,"published":"2026-03-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-18","vendors":["SGLang"]},"summary":"Remote attackers can execute arbitrary code via pickle deserialization in the SGLang multimodal generation runtime scheduler's default network configuration.","url":"https://insights.sbomify.com/CVE-2026-7301/"}
