CVE-2026-24330
Description
A flaw was found in wildfly-core. A remote attacker, authenticated as a 'deployer' account, can import and deploy a malicious archive file from an untrusted source. This is achieved by leveraging WildFly libraries to craft a Java project that allows an HTTP POST request to upload and deploy the malicious archive. This could lead to further exploitation, such as arbitrary file read vulnerabilities.
Statement
This vulnerability is rated Moderate for Red Hat products as it requires an attacker to be authenticated as a 'deployer' account. An authenticated attacker could deploy a malicious archive, potentially leading to arbitrary file read vulnerabilities.
Mitigation
To mitigate this vulnerability, restrict access to the 'deployer' account to only authorized and trusted administrators. Implement strong authentication policies for this account and consider limiting its permissions to prevent the deployment of untrusted applications. Ensure that the WildFly management interfaces are not exposed to untrusted networks and that only verified and signed applications are permitted for deployment. If the 'deployer' role is not strictly necessary, consider disabling or removing it. Changes to WildFly configuration may require a service restart to take effect.
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).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
Arbitrary code execution is possible if an uploaded file is interpreted and executed as code by the recipient. This is especially true for web-server extensions such as .asp and .php because these file types are often treated as automatically executable, even when file system permissions do not specify execution. For example, in Unix environments, programs typically cannot run unless the execute bit is set, but PHP programs may be executed by the web server without directly invoking them on the operating system.
