Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-19509 in the wild and no public exploit code.\n\nAffected product: RDK-B WebUI. 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-2026-19509/ (Markdown: https://insights.sbomify.com/CVE-2026-19509/index.md)","id":"CVE-2026-19509","markdown":"https://insights.sbomify.com/CVE-2026-19509/index.md","name":"CVE-2026-19509","record":{"aliases":["GHSA-59c8-jrwr-rjrp"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"RDK-B WebUI","requires_auth":"low_privilege","summary":"An authenticated attacker can cause a denial of service in RDK-B WebUI by sending a crafted ssid_number parameter due to improper input validation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper input validation in `ajaxSet_wireless_network_configuration.jst` in RDK-B WebUI `rdkb-2025q4-kirkstone.04.10.26` allows an authenticated attacker to cause denial of service via a crafted `ssid_number` parameter.","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":"RDK WebUI DOS vulnerability","id":"CVE-2026-19509","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Gravity Forms \u003c= 3.0.2 - Unauthenticated Arbitrary File Upload via State/Chunk Hash Confusion","id":"CVE-2026-19513"},"packages":[],"prev":{"headline":"RDK WebUI heap-based buffer overflow vulnerability","id":"CVE-2026-19508"},"products":["RDK-B WebUI"],"published":"2026-08-19","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":"2026-08-27","vendors":["RDK"]},"summary":"An authenticated attacker can cause a denial of service in RDK-B WebUI by sending a crafted ssid_number parameter due to improper input validation.","url":"https://insights.sbomify.com/CVE-2026-19509/"}
