Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.73% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs nats-io nats-server and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Cross-source reconciliation

Remediation availability differs by product scope

Verified remediation exists for at least one product or source, but 2 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Distribution package intelligence

Release-specific package status

Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.

5 package states
Package result overrides the generic status

BlackTree has verified remediation for at least one product or source, but the relevant distribution still reports no fixed package for 2 affected package states shown here. Treat those rows as affected with no fix until that distribution publishes a fixed version.

Repository candidate not checked

A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

Summary
A flaw was found in nats-server. The WebSockets implementation fails to enforce a memory allocation limit during the decompression of WebSocket messages. A malicious compressed payload allows an attacker to cause an excessive memory consumption, eventually resulting in a server crash and a complete denial of service.

01

What, why and how

NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. The WebSockets handling of NATS messages handles compressed messages via the WebSockets negotiated compression. Prior to versions 2.11.2 and 2.12.3, the implementation bound the memory size of a NATS message but did not independently bound the memory consumption of the memory stream when constructing a NATS message which might then fail validation for size reasons. An attacker can use a compression bomb to cause excessive memory consumption, often resulting in the operating system terminating the server process. The use of compression is negotiated before authentication, so this does not require valid NATS credentials to exploit. The fix, present in versions 2.11.2 and 2.12.3, was to bounds the decompression to fail once the message was too large, instead of continuing on. The vulnerability only affects deployments which use WebSockets and which expose the network port to untrusted end-points.

The vulnerability only affects deployments which use WebSockets and which expose the network port to untrusted end-points.

Why

The product does not handle or incorrectly handles a compressed input with a very high compression ratio that produces a large output.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Improper Handling of Highly Compressed Data (Data Amplification) → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Network
Privileges required
None: unauthenticated exploitation is possible
User interaction

Attack complexity
High: exploitation depends on specific conditions
Security boundary

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-409 ↗

CWE-409: Improper Handling of Highly Compressed Data (Data Amplification). The product does not handle or incorrectly handles a compressed input with a very high compression ratio that produces a large output.

JVN iPedia · Japanese · JVNDB-2026-005586Linux Foundationのnats-serverにおける複数の脆弱性

NATS-Serverは、NATS.ioのための高性能サーバーであり、クラウドおよびエッジネイティブのメッセージングシステムです。NATSメッセージのWebSocketsによる処理は、WebSocketsでネゴシエートされた圧縮を通じて圧縮メッセージを処理します。バージョン2.11.2および2.12.3より前では、実装がNATSメッセージのメモリサイズに制限を設けていましたが、NATSメッセージを構築する際のメモリストリームのメモリ消費を独立して制限していませんでした。これにより、サイズの検証に失敗する可能性がありました。攻撃者は圧縮爆弾を利用して過剰なメモリ消費を引き起こし、多くの場合、オペレーティングシステムがサーバープロセスを終了させる結果になります。圧縮の使用は認証前にネゴシエートされるため、この脆弱性を悪用するために有効なNATSの認証情報は不要です。バージョン2.11.2および2.12.3での修正は、メッセージが大きすぎる場合に継続せずに解凍を失敗させるように制限を設けたことです。この脆弱性は、WebSocketsを使用し、かつネットワークポートを信頼できないエンドポイントに公開しているデプロイメントにのみ影響します。
