Exploitation evidence

Disclosed: evidence found.
CVE published 14 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

A security update for Red Hat build of Quarkus 3.20.3 is available that addresses these vulnerabilities. Red Hat advises applying this update after ensuring all previously released errata relevant to your system have been applied. Detailed update instructions are available in the Red Hat advisory RHSA-2025:17563 and related documentation. No alternative mitigations or workarounds are specified.

Description

This release of Red Hat build of Quarkus 3.20.3 includes the following CVE fixes: * netty-codec-http: Netty is vulnerable to request smuggling due to incorrect parsing of chunk extensions [quarkus-3.20] (CVE-2025-58056) * netty-codec: Netty's BrotliDecoder is vulnerable to DoS via zip bomb style attack [quarkus-3.20] (CVE-2025-58057) For more information, see the release notes page listed in the References section.

Impact

Successful exploitation of CVE-2025-58056 could allow an attacker to perform HTTP request smuggling attacks, potentially bypassing security controls or interfering with HTTP traffic processing. CVE-2025-58057 could allow denial-of-service conditions via specially crafted compressed data causing resource exhaustion. Both vulnerabilities affect the underlying Netty components used in the Red Hat build of Quarkus 3.20.3, impacting applications relying on this runtime. No known exploits in the wild have been reported at this time.

Summary

This advisory covers two vulnerabilities fixed in Red Hat build of Quarkus 3.20.3. CVE-2025-58056 is a request smuggling vulnerability in Netty's HTTP/2 and HTTP codec modules caused by incorrect parsing of chunk extensions. CVE-2025-58057 is a denial-of-service vulnerability in Netty's BrotliDecoder due to zip bomb style attacks. The update includes these fixes and other component version bumps to improve security and stability. Red Hat rates the security impact as moderate and recommends applying the update after ensuring all prior errata are applied.

CWE-444Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') (opens in a new tab)
Base weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product acts as an intermediary HTTP agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed HTTP requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination.
Implementation
Use a web server that employs a strict HTTP parsing procedure, such as Apache.
Implementation
Use only SSL communication.
Implementation
Terminate the client session after each request.
