Versions 4.7.0 through 4.10.16 used an unbounded ConcurrentHashMap cache with no eviction policy in its DefaultHtmlErrorResponseBodyProvider. If the application throws an exception whose message may be influenced by an attacker, (for example, including request query value parameters) it could be used by remote attackers to cause an unbounded heap growth and OutOfMemoryError, leading to DoS. This issue has been fixed in version 4.10.7.","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/micronaut-projects/micronaut-core/commit/1e2ba2c14386af3d47751732d02053a72b0b49b3","https://github.com/micronaut-projects/micronaut-core/releases/tag/v4.10.17","https://github.com/micronaut-projects/micronaut-core/security/advisories/GHSA-2hcp-gjrf-7fhc"],"products":["objectcomputing:micronaut"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33012","score":0.00571,"percentile":0.47248,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2hcp-gjrf-7fhc","url":"https://osv.dev/vulnerability/GHSA-2hcp-gjrf-7fhc","summary":"Micronaut Framework vulnerable to a Denial of Service in HTML error response caching","modified":"2026-09-10T03:50:36.483039311Z","packages":[{"ecosystem":"Maven","name":"io.micronaut:micronaut-http-server","purl":"pkg:maven/io.micronaut/micronaut-http-server","ranges":[">=4.7.0 <4.10.17"],"fixed":["4.10.17"]}]}],"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).
