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-2026-1949 in the wild and no public exploit code.\n\nAffected product: DeltaWW AS320T. 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-2026-1949/ (Markdown: https://insights.sbomify.com/CVE-2026-1949/index.md)","id":"CVE-2026-1949","markdown":"https://insights.sbomify.com/CVE-2026-1949/index.md","name":"CVE-2026-1949","record":{"aliases":["GHSA-9rv5-7gpw-9g55"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Delta AS320T PLC","requires_auth":"none","summary":"Incorrect buffer size calculation in the web service handler allows attackers to cause stack-based memory corruption, potentially leading to code execution or denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Deltaww","cpe":[{"product":"as320t_firmware","vendor":"deltaww"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-131","name":"Incorrect Calculation of Buffer Size"}],"description":"Delta Electronics AS320T has incorrect calculation of the buffer size on the stack in the GET/PUT request handler of the web service.","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":"Incorrect calculation of buffer size on the stack in AS320T","id":"CVE-2026-1949","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"No checking of the length of the buffer with the file name in AS320T","id":"CVE-2026-1950"},"packages":[],"prev":{"headline":"Missing authorization in NEX-Forms – Ultimate Forms Plugin for WordPress","id":"CVE-2026-1948"},"products":["AS320T"],"published":"2026-04-24","related":[{"cvss_score":9.8,"headline":"No checking of the length of the buffer with the file name in AS320T","id":"CVE-2026-1950","kev_date_added":null,"published":"2026-04-24"},{"cvss_score":9.8,"headline":"No checking of the length of the buffer with the directory name in AS320T","id":"CVE-2026-1951","kev_date_added":null,"published":"2026-04-24"},{"cvss_score":9.8,"headline":"Denial of service via the undocumented subfunction in AS320T","id":"CVE-2026-1952","kev_date_added":null,"published":"2026-04-24"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-24","vendors":["DeltaWW"]},"summary":"Incorrect buffer size calculation in the web service handler allows attackers to cause stack-based memory corruption, potentially leading to code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2026-1949/"}
