It can only be exploited from the same machine or local network, 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-2026-58304 exists.\n\nAffected product: Samsung Open Source Escargot. 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-2026-58304/ (Markdown: https://insights.sbomify.com/CVE-2026-58304/index.md)","id":"CVE-2026-58304","markdown":"https://insights.sbomify.com/CVE-2026-58304/index.md","name":"CVE-2026-58304","record":{"aliases":["GHSA-2f23-fgrf-4r2h"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"JavaScript engine library","requires_auth":"none","summary":"Out-of-bounds read and write in the Escargot JavaScript engine allow attackers to cause memory corruption, potentially leading to code execution or crashes.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"samsung.tv_appliance","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Out-of-bounds read, Out-of-bounds write vulnerability in Samsung Open Source Escargot allows Overflow Buffers.\n\nThis issue affects Escargot: before 779f6bedf58f334dec64b0a51ebb724b4708b84a.","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":"Memory corruption in Escargot","id":"CVE-2026-58304","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in Escargot","id":"CVE-2026-58305"},"packages":[],"prev":{"headline":"Memory corruption in Escargot","id":"CVE-2026-58303"},"products":["Escargot"],"published":"2026-07-09","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)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-09","vendors":["Samsung Open Source"]},"summary":"Out-of-bounds read and write in the Escargot JavaScript engine allow attackers to cause memory corruption, potentially leading to code execution or crashes.","url":"https://insights.sbomify.com/CVE-2026-58304/"}
