CVE-2025-49574
Description
A data leak vulnerability has been discovered in the io.quarkus:quarkus-vertx package. This flaw can lead to information disclosure if a Vert.x context that has already been duplicated is subsequently duplicated again. In such a scenario, sensitive data residing within that context may be unintentionally exposed.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
An adversary that gains access to a resource exposed to a wrong sphere could potentially retrieve private data from that resource, thus breaking the intended confidentiality of that data.
Integrity
Technical Impact: Modify Application Data
An adversary that gains access to a resource exposed to a wrong sphere could potentially modify data held within that resource, thus breaking the intended integrity of that data and causing the system relying on that resource to make unintended decisions.
Other
Technical Impact: Varies by Context
The consequences may vary widely depending on how the product uses the affected resource.
