Tapo C100 v5, published on 2 Apr 2026. 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-2026-34118 in the wild and no public exploit code.\n\nAffected product: TP Link Systems Inc. Tapo C100 v5. 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-2026-34118/ (Markdown: https://insights.sbomify.com/CVE-2026-34118/index.md)","id":"CVE-2026-34118","markdown":"https://insights.sbomify.com/CVE-2026-34118/index.md","name":"CVE-2026-34118","record":{"aliases":["GHSA-v6p2-mjh5-mvpm"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TP-Link Tapo camera","requires_auth":"none","summary":"A heap-based buffer overflow in TP-Link Tapo cameras allows network attackers to cause a denial-of-service condition via crafted HTTP requests.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TPLink","cpe":[{"product":"tapo_c520ws_firmware","vendor":"tp-link"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A heap-based buffer overflow vulnerability was identified in TP-Link Tapo C100/C101 v5, C210 v3.6 and C520WS v2.6 in the HTTP POST body parsing logic due to missing validation of remaining buffer capacity after dynamic allocation, due to insufficient boundary validation when handling externally supplied HTTP input.  \n\nAn attacker\non the same network segment could trigger heap memory corruption conditions by\nsending crafted payloads that cause write operations beyond allocated buffer\nboundaries.  Successful exploitation\ncauses a Denial-of-Service (DoS) condition, causing the device’s process to\ncrash or become unresponsive.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Heap-based Buffer Overflow Vulnerability Leading to Denial-of-Service in TP-Link Tapo C100, C101, C210 \u0026 C520WS","id":"CVE-2026-34118","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"Heap-based Buffer Overflow Vulnerability Leading to Denial-of-Service in TP-Link Tapo C520WS","id":"CVE-2026-34119"},"packages":[],"prev":{"headline":"Guardian Language-System Unauthenticated OS Command Injection via id Parameter in text_to_subtitles.php","id":"CVE-2026-34117"},"products":["Tapo C100 v5","Tapo C101 v5","Tapo C210 v3","Tapo C520WS v2.6"],"published":"2026-04-02","related":[{"cvss_score":8.7,"headline":"Authentication Bypass in DS Configuration Service via HTTP Request Parsing Differential of TP-Link Tapo C520WS","id":"CVE-2026-34121","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.1,"headline":"Denial-of-Service Vulnerability in RTSP Input Handling on TP-Link's Tapo C520WS","id":"CVE-2026-8714","kev_date_added":null,"published":"2026-06-05"},{"cvss_score":7.1,"headline":"Heap-based Buffer Overflow Vulnerability Leading to Denial-of-Service in TP-Link Tapo C520WS","id":"CVE-2026-34119","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.1,"headline":"Heap-based Buffer Overflow Vulnerability Leading to Denial-of-Service in TP-Link Tapo C520WS","id":"CVE-2026-34120","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.1,"headline":"Stack-based Buffer Overflow Leading to Denial of Service in TP-Link Tapo C520WS","id":"CVE-2026-34122","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.1,"headline":"Denial of Service via Path Expansion Overflow in HTTP Service in TP-Link Tapo C520WS","id":"CVE-2026-34124","kev_date_added":null,"published":"2026-04-02"}],"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":"2026-10-19","vendors":["TP Link Systems Inc.","TP-Link Systems Inc."]},"summary":"A heap-based buffer overflow in TP-Link Tapo cameras allows network attackers to cause a denial-of-service condition via crafted HTTP requests.","url":"https://insights.sbomify.com/CVE-2026-34118/"}
