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-2026-15976 exists.\n\nAffected product: SGLang. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-15976/ (Markdown: https://insights.sbomify.com/CVE-2026-15976/index.md)","id":"CVE-2026-15976","markdown":"https://insights.sbomify.com/CVE-2026-15976/index.md","name":"CVE-2026-15976","record":{"aliases":["GHSA-r344-357p-w9pp","GHSA-wf98-gv64-5wrf"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SGLang LLM library","requires_auth":"none","summary":"Attackers can execute arbitrary code by loading malicious model weights from a HuggingFace repository due to unsafe pickle deserialization.","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":"SGLang contains a RCE vulnerability when attempting to load model weights from a HuggingFace repository, specifically within the /update_weights_from_disk, where torch.load(..., weights_only=False) fallback enables pickle deserialization of .bin files.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"CVE-2026-15976","id":"CVE-2026-15976","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"CVE-2026-15977","id":"CVE-2026-15977"},"packages":[],"prev":{"headline":"Allocation of Resources Without Limits or Throttling in GitLab","id":"CVE-2026-15975"},"products":["SGLang"],"published":"2026-07-30","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-2026-7301","id":"CVE-2026-7301","kev_date_added":null,"published":"2026-05-18"},{"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":"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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-31","vendors":["SGLang"]},"summary":"Attackers can execute arbitrary code by loading malicious model weights from a HuggingFace repository due to unsafe pickle deserialization.","url":"https://insights.sbomify.com/CVE-2026-15976/"}
