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-2026-63559 in the wild and no public exploit code.\n\nAffected product: o6 Automation open62541. 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-2026-63559/ (Markdown: https://insights.sbomify.com/CVE-2026-63559/index.md)","id":"CVE-2026-63559","markdown":"https://insights.sbomify.com/CVE-2026-63559/index.md","name":"CVE-2026-63559","record":{"aliases":["DEBIAN-CVE-2026-63559","GHSA-6c97-xqf2-q99q","UBUNTU-CVE-2026-63559"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OPC UA library","requires_auth":"none","summary":"A remote attacker can exploit an integer overflow in open62541 to read out-of-bounds heap memory and disclose sensitive information.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An integer overflow in the UA_Variant arrayDimensions product \ncomputation in open62541 may allow a remote attacker to read \nout-of-bounds heap memory, potentially disclosing sensitive information.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"o6 Automation open62541 Integer Overflow or Wraparound","id":"CVE-2026-63559","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"Misconfiguration in Sharp MFPs","id":"CVE-2026-63563"},"packages":[],"prev":{"headline":"MZ Automation libiec61850 Out-of-bounds Read","id":"CVE-2026-63550"},"products":["open62541"],"published":"2026-07-30","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-25","vendors":["o6 Automation"]},"summary":"A remote attacker can exploit an integer overflow in open62541 to read out-of-bounds heap memory and disclose sensitive information.","url":"https://insights.sbomify.com/CVE-2026-63559/"}
