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-2026-9758 in the wild and no public exploit code.\n\nAffected product: Systerel S2OPC. 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-2026-9758/ (Markdown: https://insights.sbomify.com/CVE-2026-9758/index.md)","id":"CVE-2026-9758","markdown":"https://insights.sbomify.com/CVE-2026-9758/index.md","name":"CVE-2026-9758","record":{"aliases":["GHSA-q89f-427x-5p67"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"S2OPC OPC UA library","requires_auth":"none","summary":"Attackers can bypass certificate validation in S2OPC by presenting untrusted certificates, undermining secure communication trust.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"Improper comparison with the certificates trusted list in S2OPC allows an attacker well-formed untrusted certificate to be considered trusted","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 Certificate Validation in S2OPC","id":"CVE-2026-9758","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"NULL Pointer Dereference in Wireshark","id":"CVE-2026-9759"},"packages":[],"prev":{"headline":"GEO my WP \u003c= 4.5.5 - Unauthenticated SQL Injection via 'swlatlng' / 'nelatlng' Parameters","id":"CVE-2026-9757"},"products":["S2OPC"],"published":"2026-06-10","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":"2026-06-10","vendors":["Systerel"]},"summary":"Attackers can bypass certificate validation in S2OPC by presenting untrusted certificates, undermining secure communication trust.","url":"https://insights.sbomify.com/CVE-2026-9758/"}
