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-2026-75935 in the wild and no public exploit code.\n\nAffected product: Amazon Ion Java. 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-2026-75935/ (Markdown: https://insights.sbomify.com/CVE-2026-75935/index.md)","id":"CVE-2026-75935","markdown":"https://insights.sbomify.com/CVE-2026-75935/index.md","name":"CVE-2026-75935","record":{"aliases":["GHSA-822f-6gg9-whr5"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java Ion library","requires_auth":"none","summary":"Remote attackers can cause denial of service in applications using Amazon ion-java by sending crafted binary documents that trigger excessive memory allocation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/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-789","name":"Memory Allocation with Excessive Size Value"}],"description":"Uncontrolled memory allocation in the binary Ion stream cursor in Amazon ion-java before 1.12.0 might allow remote actors to cause a denial of service via a crafted Ion binary document containing a declared-length field that causes excessive heap preallocation.\n\nTo remediate this issue, users should upgrade to version 1.12.0.","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":"Memory-amplification denial of service via declared-length preallocation in Amazon ion-java","id":"CVE-2026-75935","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Memory-amplification denial of service via GZIP decompression bomb in Amazon ion-java","id":"CVE-2026-75936"},"packages":[],"prev":{"headline":"Jet Admin Stored XSS","id":"CVE-2026-75933"},"products":["Amazon Ion Java"],"published":"2026-08-18","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":"2026-08-19","vendors":["Amazon Ion"]},"summary":"Remote attackers can cause denial of service in applications using Amazon ion-java by sending crafted binary documents that trigger excessive memory allocation.","url":"https://insights.sbomify.com/CVE-2026-75935/"}
