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-2025-65570 exists.\n\nAffected product: Jsish Jsish. 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-2025-65570/ (Markdown: https://insights.sbomify.com/CVE-2025-65570/index.md)","id":"CVE-2025-65570","markdown":"https://insights.sbomify.com/CVE-2025-65570/index.md","name":"CVE-2025-65570","record":{"aliases":["GHSA-r6xg-3mr4-3226"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"jsish JavaScript engine","requires_auth":"none","summary":"A type confusion in the jsish JavaScript engine allows attackers to cause crashes or execute arbitrary code via crafted instanceof expressions in for-in loops.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jsish","vendor":"jsish"}],"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-843","name":"Access of Resource Using Incompatible Type"}],"description":"A type confusion in jsish 2.0 allows incorrect control flow during execution of the OP_NEXT opcode. When an “instanceof” expression uses an array element access as the left-hand operand inside a for-in loop, the instructions implementation leaves an additional array reference on the stack rather than consuming it during OP_INSTANCEOF. As a result, OP_NEXT interprets the array as an iterator object and reads the iterCmd function pointer from an invalid structure, potentially causing a crash or enabling code execution depending on heap layout.","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 n/a","id":"CVE-2025-65570","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jsish:jsish","products":["jsish:jsish"],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2025-65572"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2025-65568"},"products":["n/a"],"published":"2025-12-29","related":[{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2024-24186","kev_date_added":null,"published":"2024-02-07"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-24188","kev_date_added":null,"published":"2024-02-07"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2024-24189","kev_date_added":null,"published":"2024-02-07"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-22873","kev_date_added":null,"published":"2021-07-13"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2020-22874","kev_date_added":null,"published":"2021-07-13"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2020-22875","kev_date_added":null,"published":"2021-07-13"}],"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":"2025-12-31","vendors":["n/a"]},"summary":"A type confusion in the jsish JavaScript engine allows attackers to cause crashes or execute arbitrary code via crafted instanceof expressions in for-in loops.","url":"https://insights.sbomify.com/CVE-2025-65570/"}
