Exploitation evidence

CVE published 17 Mar 2026
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.

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Red Hat has released an official fix in JBoss Enterprise Application Platform version 8.1.5. Users should update to this version to remediate the vulnerability. Alternatively, a mitigation is available by disabling the static handler cache via configuration (e.g., using StaticHandler.create().setCachingEnabled(false)). Before updating, ensure all prior errata are applied and back up existing installations.

Description

A vulnerability in Red Hat JBoss Enterprise Application Platform versions prior to 8.1.5 allows remote attackers to cause a denial of service by manipulating the Vert.x Web static handler cache. This manipulation results in legitimate users receiving HTTP 404 responses when accessing static files such as images, CSS, or HTML. The underlying server and API endpoints remain unaffected. Red Hat has released version 8.1.5 to address this issue.

Impact

The vulnerability allows remote attackers to deny access to specific static files served by the application platform, such as images, CSS, or HTML files, by causing the server to respond with HTTP 404 errors. This results in a denial of service for those static resources but does not impact the availability or integrity of the underlying Vert.x server or API endpoints.

Summary

CVE-2026-1002 is a vulnerability in the Vert.x Web static handler component used by Red Hat JBoss Enterprise Application Platform. An attacker can manipulate the static handler cache via crafted request URIs to block access to static files, causing denial of service by returning HTTP 404 errors for those files. This does not affect the Vert.x server itself or API endpoints. The vulnerability has been rated with moderate severity due to its limited impact. Red Hat fixed this issue in version 8.1.5 of JBoss Enterprise Application Platform.
