Versions prior to both 4.10.16 and 3.10.5 do not correctly handle descending array index order during form-urlencoded body binding in theJsonBeanPropertyBinder::expandArrayToThreshold, which allows remote attackers to cause a DoS (non-terminating loop, CPU exhaustion, and OutOfMemoryError) via crafted indexed form parameters (e.g., authors[1].name followed by authors[0].name). This issue has been fixed in versions 4.10.16 and 3.10.5.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.2},"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-835"],"references":["https://github.com/micronaut-projects/micronaut-core/commit/1afe509677c51b320041b7a2c177366d4a4deb55","https://github.com/micronaut-projects/micronaut-core/pull/12410","https://github.com/micronaut-projects/micronaut-core/releases/tag/v3.10.5","https://github.com/micronaut-projects/micronaut-core/releases/tag/v4.10.16","https://github.com/micronaut-projects/micronaut-core/security/advisories/GHSA-43w5-mmxv-cpvh"],"products":["objectcomputing:micronaut"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33013","score":0.00605,"percentile":0.48983,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-43w5-mmxv-cpvh","url":"https://osv.dev/vulnerability/GHSA-43w5-mmxv-cpvh","summary":"Micronaut vulnerable to DoS via crafted form-urlencoded body binding with descending array indices","modified":"2026-09-10T03:50:37.020958900Z","packages":[{"ecosystem":"Maven","name":"io.micronaut:micronaut-json-core","purl":"pkg:maven/io.micronaut/micronaut-json-core","ranges":[">=4.0.0-M1 <4.10.16"],"fixed":["4.10.16"]},{"ecosystem":"Maven","name":"io.micronaut:micronaut-json-core","purl":"pkg:maven/io.micronaut/micronaut-json-core","ranges":[">=3.9.0 <3.10.5"],"fixed":["3.10.5"]},{"ecosystem":"Maven","name":"io.micronaut:micronaut-json-core","purl":"pkg:maven/io.micronaut/micronaut-json-core","ranges":["<3.8.13"],"fixed":["3.8.13"]}]}],"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).
