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-2026-31048 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2026-31048/ (Markdown: https://insights.sbomify.com/CVE-2026-31048/index.md)","id":"CVE-2026-31048","markdown":"https://insights.sbomify.com/CVE-2026-31048/index.md","name":"CVE-2026-31048","record":{"aliases":["UBUNTU-CVE-2026-31048"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Pyro RPC library","requires_auth":"none","summary":"Attackers can execute arbitrary code by sending crafted pickled messages to applications using the Pyro v3.x library.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"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-94","name":"Improper Control of Generation of Code"}],"description":"An issue in the \u003ccode\u003epickle\u003c/code\u003e protocol of Pyro v3.x allows attackers to execute arbitrary code via supplying a crafted pickled string message.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-04-10","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-04-10T16:25:41Z","kind":"github_poc","ref":"https://github.com/Sif-0x01/security-advisories","stars":0,"title":"Security advisory for CVE-2026-31048"}],"tier":"poc_unverified"},"has_fix":false,"headline":"Deserialization in n/a","id":"CVE-2026-31048","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Code injection in n/a","id":"CVE-2026-31049"},"packages":[],"prev":{"headline":"stata-mcp has insufficient validation of user-supplied Stata do-file content that can lead to command execution","id":"CVE-2026-31040"},"products":["n/a"],"published":"2026-04-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-15","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code by sending crafted pickled messages to applications using the Pyro v3.x library.","url":"https://insights.sbomify.com/CVE-2026-31048/"}
