TL-WR841N v14, published on 26 Mar 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-2026-3622 in the wild and no public exploit code.\n\nAffected product: TP-Link Systems Inc. TL-WR841N v14. 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-2026-3622/ (Markdown: https://insights.sbomify.com/CVE-2026-3622/index.md)","id":"CVE-2026-3622","markdown":"https://insights.sbomify.com/CVE-2026-3622/index.md","name":"CVE-2026-3622","record":{"aliases":["GHSA-hhj2-6q7v-v5hc"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TP-Link router","requires_auth":"none","summary":"An out-of-bounds read in the UPnP component allows attackers to crash the service, causing a denial of service on TP-Link routers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TPLink","cpe":[{"product":"tl-wr841n_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-125","name":"Out-of-bounds Read"}],"description":"The vulnerability exists in the UPnP component of TL-WR841N v14, where improper input validation leads to an out-of-bounds read, potentially causing a crash of the UPnP service.  \n\nSuccessful exploitation can cause the UPnP service to crash, resulting in a Denial-of-Service condition. \nThis vulnerability affects TL-WR841N v14 \u003c EN_0.9.1 4.19 Build 260303 Rel.42399n (V14_260303) and \u003c US_0.9.1.4.19 Build 260312 Rel. 49108n (V14_0304).","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":"Denial-of-Service Vulnerability in UPnP Component of TP Link's TL-WR841N","id":"CVE-2026-3622","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Vulnerabilities exists in IBM Netezza Performance Server Replication Services","id":"CVE-2026-3623"},"packages":[],"prev":{"headline":"IBM WebSphere Application Server Liberty is affected by identity spoofing","id":"CVE-2026-3621"},"products":["TL-WR841N v14"],"published":"2026-03-26","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-25073","kev_date_added":null,"published":"2022-02-22"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2018-12575","kev_date_added":null,"published":"2018-07-02"},{"cvss_score":8.8,"headline":"File upload in n/a","id":"CVE-2022-46912","kev_date_added":null,"published":"2022-12-20"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2020-35576","kev_date_added":null,"published":"2021-01-25"},{"cvss_score":8.8,"headline":"Memory corruption in TL-WR841N","id":"CVE-2019-17147","kev_date_added":null,"published":"2020-01-07"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2018-12574","kev_date_added":null,"published":"2018-07-02"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2018-12577","kev_date_added":null,"published":"2018-07-02"}],"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":"2026-03-27","vendors":["TP-Link Systems Inc."]},"summary":"An out-of-bounds read in the UPnP component allows attackers to crash the service, causing a denial of service on TP-Link routers.","url":"https://insights.sbomify.com/CVE-2026-3622/"}
