It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-45160 in the wild and no public exploit code.\n\nAffected product: espressif esp-idf. 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-2026-45160/ (Markdown: https://insights.sbomify.com/CVE-2026-45160/index.md)","id":"CVE-2026-45160","markdown":"https://insights.sbomify.com/CVE-2026-45160/index.md","name":"CVE-2026-45160","record":{"aliases":["GHSA-g764-gwc3-75m5"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Espressif IoT framework","requires_auth":"none","summary":"A crafted DHCP request can cause an out-of-bounds read in the ESP-IDF DHCP server, potentially leaking adjacent heap memory.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"esp-idf","vendor":"espressif"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.2.7, 5.3.5, 5.4.4, 5.5.4, and 6.0.1, an out-of-bounds read flaw exists in the DHCP server option parser (parse_options() in components/lwip/apps/dhcpserver/dhcpserver.c) shipped with ESP-IDF's lwIP component. The parser walks the BOOTP/DHCP options field without validating that each option's length byte and declared payload length stay within the received packet buffer. A crafted DHCP request can cause the parser to read past the end of the options buffer into adjacent heap memory. The issue affects the DHCP server used by ESP-IDF's SoftAP and any configuration where the device runs as a DHCP server on a local network. This issue has been patched in versions 5.2.8, 5.3.6, 5.4.5, 5.5.5, and 6.0.2.","ecosystems":[],"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":"ESF-IDF: Out-of-bounds Read in lwIP DHCP Server Option Parser","id":"CVE-2026-45160","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"wger: trainer_login accepts GET - CSRF bypass enables forced session rebinding","id":"CVE-2026-45161"},"packages":[],"prev":{"headline":"Missing authorization in security-advisories","id":"CVE-2026-45159"},"products":["esp-idf"],"published":"2026-06-10","related":[{"cvss_score":9.3,"headline":"ESF-IDF: Out-of-Bounds Write in ESP-TEE Secure Service Wrappers","id":"CVE-2026-45328","kev_date_added":null,"published":"2026-06-10"},{"cvss_score":8.8,"headline":"Auth bypass in n/a","id":"CVE-2024-53406","kev_date_added":null,"published":"2025-03-13"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2021-28139","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":8.1,"headline":"Information disclosure in n/a","id":"CVE-2024-33453","kev_date_added":null,"published":"2024-10-17"},{"cvss_score":8.1,"headline":"Weak cryptography in n/a","id":"CVE-2019-12587","kev_date_added":null,"published":"2019-09-04"},{"cvss_score":7.5,"headline":"ESF-IDF: Remote Null Pointer Dereference in WebSocket Server","id":"CVE-2026-45541","kev_date_added":null,"published":"2026-06-10"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2024-51428","kev_date_added":null,"published":"2024-11-07"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-10","vendors":["espressif"]},"summary":"A crafted DHCP request can cause an out-of-bounds read in the ESP-IDF DHCP server, potentially leaking adjacent heap memory.","url":"https://insights.sbomify.com/CVE-2026-45160/"}
