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-2026-3631 in the wild and no public exploit code.\n\nAffected product: DeltaWW COMMGR2. 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-2026-3631/ (Markdown: https://insights.sbomify.com/CVE-2026-3631/index.md)","id":"CVE-2026-3631","markdown":"https://insights.sbomify.com/CVE-2026-3631/index.md","name":"CVE-2026-3631","record":{"aliases":["GHSA-q5cv-phmc-fwgp"],"analysis":{"component_type":"desktop_application","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Delta COMMGR2","requires_auth":"none","summary":"A buffer over-read vulnerability in Delta Electronics COMMGR2 allows attackers to cause a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Deltaww","cpe":[{"product":"commgr2","vendor":"deltaww"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Delta Electronics COMMGR2 has \n\nBuffer Over-read DoS vulnerability.","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":"Buffer Over-read DoS Vulnerability in COMMGR2","id":"CVE-2026-3631","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Libsoup: libsoup: http smuggling and server-side request forgery via malformed hostnames","id":"CVE-2026-3632"},"packages":[],"prev":{"headline":"Stack-based Buffer Overflow Vulnerability in COMMGR2","id":"CVE-2026-3630"},"products":["COMMGR2"],"published":"2026-03-09","related":[{"cvss_score":9.8,"headline":"Stack-based Buffer Overflow Vulnerability in COMMGR2","id":"CVE-2026-3630","kev_date_added":null,"published":"2026-03-09"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-03-09","vendors":["DeltaWW"]},"summary":"A buffer over-read vulnerability in Delta Electronics COMMGR2 allows attackers to cause a denial of service.","url":"https://insights.sbomify.com/CVE-2026-3631/"}
