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-2026-13476 in the wild and no public exploit code.\n\nAffected product: Ibm Informix Dynamic Server. 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-2026-13476/ (Markdown: https://insights.sbomify.com/CVE-2026-13476/index.md)","id":"CVE-2026-13476","markdown":"https://insights.sbomify.com/CVE-2026-13476/index.md","name":"CVE-2026-13476","record":{"aliases":["GHSA-2g57-mxfj-4j65"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Informix Database","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary commands with service account privileges on IBM Informix Dynamic Server due to improper input validation.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"informix_dynamic_server","vendor":"ibm"}],"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-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"IBM Informix Dynamic Server 14.10, 15.0, and 12.10 could allow an unauthenticated user to execute arbitrary commands with service account privileges on the system due to improper validation of user supplied input.","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":"IBM Informix Wire Listener Vulnerable to Unauthenticated Remote Code Execution","id":"CVE-2026-13476","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ibm:informix_dynamic_server","products":["ibm:informix_dynamic_server"],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"IBM QRadar SIEM is vulnerable to remote code execution by privileged users","id":"CVE-2026-13477"},"packages":[],"prev":{"headline":"Denial of service via malformed HTTP/2 requests","id":"CVE-2026-13474"},"products":["Informix Dynamic Server"],"published":"2026-08-12","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2010-4070","kev_date_added":null,"published":"2010-10-25"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-2753","kev_date_added":null,"published":"2010-03-05"},{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2008-0949","kev_date_added":null,"published":"2008-03-18"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-0768","kev_date_added":null,"published":"2008-02-13"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2011-1033","kev_date_added":null,"published":"2011-02-14"},{"cvss_score":9,"headline":"Memory corruption in n/a","id":"CVE-2012-4857","kev_date_added":null,"published":"2012-12-08"},{"cvss_score":9,"headline":"Memory corruption in n/a","id":"CVE-2012-3334","kev_date_added":null,"published":"2012-09-25"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-14","vendors":["IBM"]},"summary":"Unauthenticated attackers can execute arbitrary commands with service account privileges on IBM Informix Dynamic Server due to improper input validation.","url":"https://insights.sbomify.com/CVE-2026-13476/"}
