高 7.5CVE-2026-33012 · GHSA-2hcp-gjrf-7fhc · 20/03/2026 公開 · 17/06/2026 更新

要点

CVE-2026-33012 は io.micronaut:micronaut-http-server, micronaut (objectcomputing) に影響する深刻度「高」 (CVSS 7.5) の脆弱性です。
今後30日間に悪用される確率（EPSS）：0.57%（全脆弱性の 47.3% より高い）。
対処：4.10.17 以降に更新してください。

パッケージ	影響を受けるバージョン	修正済みバージョン
io.micronaut:micronaut-http-server Maven	`≥ 4.7.0, < 4.10.17`	`4.10.17`
micronaut objectcomputing	`≥ 4.7.0, < 4.10.17`	`4.10.17`

概要

DefaultHtmlErrorResponseBodyProvider in io.micronaut:micronaut-http-server since 4.7.0 and until 4.10.7 used an unbounded ConcurrentHashMap cache with no eviction policy. If the application throws an exception whose message may be influenced by an attacker, for example, including request query value parameters, this could be used by remote attackers to cause a denial of service (unbounded heap growth and OutOfMemoryError).

Fixed via: https://github.com/micronaut-projects/micronaut-core/commit/1e2ba2c14386af3d47751732d02053a72b0b49b3

NVD の説明

Micronaut Framework is a JVM-based full stack Java framework designed for building modular, easily testable JVM applications. 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.
