Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-13257 in the wild and no public exploit code.\n\nAffected product: Ibm Datapower Gateway. 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-2026-13257/ (Markdown: https://insights.sbomify.com/CVE-2026-13257/index.md)","id":"CVE-2026-13257","markdown":"https://insights.sbomify.com/CVE-2026-13257/index.md","name":"CVE-2026-13257","record":{"aliases":["GHSA-3558-f8gc-mcgw"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM DataPower Gateway","requires_auth":"low_privilege","summary":"An authenticated user can forge signature requests due to improper verification of data authenticity in IBM DataPower Gateway.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"datapower_gateway","vendor":"ibm"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"IBM DataPower Gateway 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2 could allow an authenticated user to forge signature requests due to improper verification of data authenticity.","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 DataPower Gateway Insufficient Verification of Data Authenticity","id":"CVE-2026-13257","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ibm:datapower_gateway","products":["ibm:datapower_gateway"],"type":"other","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"IBM DataPower Gateway Cross-Site Scripting","id":"CVE-2026-13258"},"packages":[],"prev":{"headline":"Cross-site scripting in Post Grid Gutenberg Blocks – PostX","id":"CVE-2026-13253"},"products":["DataPower Gateway 10.5.0","DataPower Gateway 10.6.0","DataPower Gateway 10.6CD","DataPower Gateway 11.0.0"],"published":"2026-10-08","related":[{"cvss_score":9.8,"headline":"IBM DataPower Gateway Buffer Overflow","id":"CVE-2026-14269","kev_date_added":null,"published":"2026-10-08"},{"cvss_score":9.8,"headline":"IBM DataPower Gateway Improper Authentication","id":"CVE-2026-14502","kev_date_added":null,"published":"2026-10-08"},{"cvss_score":9.8,"headline":"IBM DataPower Gateway Out-of-bounds Write","id":"CVE-2026-14991","kev_date_added":null,"published":"2026-10-08"},{"cvss_score":9.8,"headline":"IBM DataPower Gateway Out-of-bounds Write","id":"CVE-2026-14992","kev_date_added":null,"published":"2026-10-08"},{"cvss_score":9.8,"headline":"IBM DataPower Gateway Out-of-bounds Write","id":"CVE-2026-15762","kev_date_added":null,"published":"2026-10-08"},{"cvss_score":9.8,"headline":"IBM DataPower Gateway Out-of-bounds Write","id":"CVE-2026-16340","kev_date_added":null,"published":"2026-10-08"},{"cvss_score":8.8,"headline":"Cross-site request forgery in DataPower Gateway","id":"CVE-2022-31773","kev_date_added":null,"published":"2022-08-26"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-10-10","vendors":["IBM"]},"summary":"An authenticated user can forge signature requests due to improper verification of data authenticity in IBM DataPower Gateway.","url":"https://insights.sbomify.com/CVE-2026-13257/"}
