{"id":"CVE-2026-29062","aliases":["GHSA-6v53-7c9g-w56r"],"url":"https://o3.security/vulnerability/CVE-2026-29062","summary":"jackson-core: Nesting Depth Constraint Bypass in `UTF8DataInputJsonParser` potentially allowing Resource Exhaustion","details":"jackson-core contains core low-level incremental (\"streaming\") parser and generator abstractions used by Jackson Data Processor. From version 3.0.0 to before version 3.1.0, the UTF8DataInputJsonParser, which is used when parsing from a java.io.DataInput source, bypasses the maxNestingDepth constraint (default: 500) defined in StreamReadConstraints. A similar issue was found in ReaderBasedJsonParser. This allows a user to supply a JSON document with excessive nesting, which can cause a StackOverflowError when the structure is processed, leading to a Denial of Service (DoS). This issue has been patched in version 3.1.0.","published":"2026-03-06T07:14:25.059Z","modified":"2026-07-22T03:57:06.333878Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"tools.jackson.core:jackson-core","fixedVersion":"3.1.0"}],"fix":{"url":"https://github.com/FasterXML/jackson-core/commit/8b25fd67f20583e75fb09564ce1eaab06cd5a902","label":"FasterXML/jackson-core@8b25fd6"},"references":[{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-29062.json"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-29062"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29062.json"},{"type":"ADVISORY","url":"https://github.com/FasterXML/jackson-core/security/advisories/GHSA-6v53-7c9g-w56r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-29062"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2445135"},{"type":"FIX","url":"https://github.com/FasterXML/jackson-core/commit/8b25fd67f20583e75fb09564ce1eaab06cd5a902"},{"type":"FIX","url":"https://github.com/FasterXML/jackson-core/pull/1554"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-22T03:57:06.333878Z"}}
