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-2026-102552 in the wild and no public exploit code.\n\nAffected product: FreeRTOS-Plus-TCP. 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-2026-102552/ (Markdown: https://insights.sbomify.com/CVE-2026-102552/index.md)","id":"CVE-2026-102552","markdown":"https://insights.sbomify.com/CVE-2026-102552/index.md","name":"CVE-2026-102552","record":{"aliases":["GHSA-h4fw-pv82-p7h5"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"FreeRTOS TCP stack","requires_auth":"none","summary":"Remote attackers can poison the DNS cache of FreeRTOS devices by forging replies, requiring an upgrade and enabling a specific configuration flag.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-940","name":"Improper Verification of Source of a Communication Channel"}],"description":"Improper verification of the source of a communication channel in the DNS resolver in Amazon FreeRTOS-Plus-TCP before V4.4.2 might allow remote third-party to insert a chosen address into the device's DNS cache via a forged DNS reply.\n\nTo remediate this issue, users should upgrade to version V4.4.2 and enable ipconfigDNS_CHECK_REPLY_SOURCE_IP.","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":"Improper verification of the source of a communication channel in FreeRTOS-Plus-TCP DNS resolver","id":"CVE-2026-102552","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of Service via Eager Array Allocation During Deserialization in Guava","id":"CVE-2026-102554"},"packages":[],"prev":{"headline":"Improper verification of the source of a communication channel in FreeRTOS-Plus-TCP Router Advertisement handling","id":"CVE-2026-102551"},"products":["FreeRTOS-Plus-TCP"],"published":"2026-10-16","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["FreeRTOS"]},"summary":"Remote attackers can poison the DNS cache of FreeRTOS devices by forging replies, requiring an upgrade and enabling a specific configuration flag.","url":"https://insights.sbomify.com/CVE-2026-102552/"}
