Prior to version 1.10.5, a potential denial-of-service issue exists in `ion-java` for applications that use `ion-java` to deserialize Ion text encoded data, or deserialize Ion text or binary encoded data into the `IonValue` model and then invoke certain `IonValue` methods on that in-memory representation. An actor could craft Ion data that, when loaded by the affected application and/or processed using the `IonValue` model, results in a `StackOverflowError` originating from the `ion-java` library. The patch is included in `ion-java` 1.10.5. As a workaround, do not load data which originated from an untrusted source or that could have been tampered with.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770"],"references":["https://github.com/amazon-ion/ion-java/security/advisories/GHSA-264p-99wq-f4j6","https://github.com/amazon-ion/ion-java/security/advisories/GHSA-264p-99wq-f4j6","https://security.netapp.com/advisory/ntap-20241108-0002/"],"products":["amazon:ion"],"source":"nvd","synced_at":"2026-10-19T21:43:38.875533635+00:00"},"epss":{"cve":"CVE-2024-21634","score":0.00827,"percentile":0.57471,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-264p-99wq-f4j6","url":"https://osv.dev/vulnerability/GHSA-264p-99wq-f4j6","summary":"Ion Java StackOverflow vulnerability","modified":"2026-09-10T03:50:09.258018779Z","packages":[{"ecosystem":"Maven","name":"com.amazon.ion:ion-java","purl":"pkg:maven/com.amazon.ion/ion-java","ranges":["<1.10.5"],"fixed":["1.10.5"]},{"ecosystem":"Maven","name":"software.amazon.ion:ion-java","purl":"pkg:maven/software.amazon.ion/ion-java","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
