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-2026-87683 in the wild and no public exploit code.\n\nAffected product: Broadcom Fabric Operating System. 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-2026-87683/ (Markdown: https://insights.sbomify.com/CVE-2026-87683/index.md)","id":"CVE-2026-87683","markdown":"https://insights.sbomify.com/CVE-2026-87683/index.md","name":"CVE-2026-87683","record":{"aliases":["GHSA-fmmw-9gq9-8xjm"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Brocade Fabric OS","requires_auth":"low_privilege","summary":"An authenticated attacker can trigger stack-based buffer overflows in the REST API, potentially causing denial of service or arbitrary code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"brocade","cpe":[{"product":"fabric_operating_system","vendor":"broadcom"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Multiple stack-based buffer overflow vulnerabilities exist in the REST API management component of Brocade Fabric OS versions prior to 10.0.1. When processing API request payloads (such as device configuration attributes or port mapping requests) the REST API service fails to properly validate incoming array counts and string lengths against internal buffer capacities. An authenticated attacker with REST API access can transmit crafted, oversized request parameters to induce memory corruption on the execution stack. This may result in a denial-of-service condition (daemon crash) or potential arbitrary code execution within the management process context.","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":"Memory corruption in Fabric OS","id":"CVE-2026-87683","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"broadcom:fabric_operating_system","products":["broadcom:fabric_operating_system"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Fabric OS","id":"CVE-2026-87684"},"packages":[],"prev":{"headline":"Command injection in Fabric OS","id":"CVE-2026-87682"},"products":["Fabric OS"],"published":"2026-10-08","related":[{"cvss_score":8.6,"headline":"Broadcom Brocade Fabric OS Code Injection","id":"CVE-2025-1976","kev_date_added":"2025-04-28","published":"2025-04-24"},{"cvss_score":8.3,"headline":"Linux Kernel Heap Out-of-Bounds Write","id":"CVE-2021-22555","kev_date_added":"2025-10-06","published":"2021-07-07"},{"cvss_score":9.8,"headline":"Command injection in Brocade Fabric OS","id":"CVE-2022-33186","kev_date_added":null,"published":"2022-12-08"},{"cvss_score":9.8,"headline":"Hardcoded credentials in Brocade Fabric OS","id":"CVE-2021-27797","kev_date_added":null,"published":"2022-02-21"},{"cvss_score":9.8,"headline":"Code injection in Brocade Fabric OS","id":"CVE-2020-15371","kev_date_added":null,"published":"2020-09-25"},{"cvss_score":9.8,"headline":"Memory corruption in Brocade Fabric OS","id":"CVE-2020-15373","kev_date_added":null,"published":"2020-09-25"},{"cvss_score":9.8,"headline":"Cross-site scripting in Brocade Fabric OS","id":"CVE-2020-15374","kev_date_added":null,"published":"2020-09-25"}],"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":"total"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["Brocade"]},"summary":"An authenticated attacker can trigger stack-based buffer overflows in the REST API, potentially causing denial of service or arbitrary code execution.","url":"https://insights.sbomify.com/CVE-2026-87683/"}
