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-2026-50103 in the wild and no public exploit code.\n\nAffected product: MZ Automation libIEC61850. 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-2026-50103/ (Markdown: https://insights.sbomify.com/CVE-2026-50103/index.md)","id":"CVE-2026-50103","markdown":"https://insights.sbomify.com/CVE-2026-50103/index.md","name":"CVE-2026-50103","record":{"aliases":["GHSA-mg79-w9qx-hwj2"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IEC 61850 library","requires_auth":"none","summary":"A network-adjacent attacker can crash a subscribing application by sending a crafted GOOSE frame with a malformed TLV value.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"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-228","name":"Improper Handling of Syntactically Invalid Structure"}],"description":"A NULL pointer dereference in the L2 GOOSE and R-GOOSE shared parser, which may allow a network-adjacent attacker to crash a subscribing application by sending a crafted GOOSE frame containing a malformed TLV value.","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":"Improper Handling of Syntactically Invalid Structure in MZ Automation libIEC61850","id":"CVE-2026-50103","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"RSS/Atom feed handlers bypass API-token scope \u0026 public-only confinement (incomplete fix of #37698)","id":"CVE-2026-50105"},"packages":[],"prev":{"headline":"Naxclow IoT Platform Not using password aging","id":"CVE-2026-50101"},"products":["libIEC61850"],"published":"2026-07-23","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":"2026-07-24","vendors":["MZ Automation"]},"summary":"A network-adjacent attacker can crash a subscribing application by sending a crafted GOOSE frame with a malformed TLV value.","url":"https://insights.sbomify.com/CVE-2026-50103/"}
