CVE-2026-85634— Wildfly-core: wildfly-core: deployer rbac role privilege escalation via path traversal in deployment name

Quick assessment

Affected
Red Hat Red Hat Fuse 7
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 WildFly 和 JBoss EAP 用于管理服务器部署的 wildfly-core 库中，ContentRepositoryImpl.copyExplodedContent 函数存在一个缺陷。该问题发生在库处理未经清理的部署名称时。由于缺少容器检查，具有 Deployer RBAC 角色的攻击者可以利用路径遍历序列访问受限部署目录之外的文件。这使得攻击者能够删除任意目录或创建具有任意内容的文件，从而导致完全权限升级到管理 SuperUser 角色。

Vulnerability Title
Wildfly-core: wildfly-core: deployer rbac role privilege escalation via path traversal in deployment name
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the ContentRepositoryImpl.copyExplodedContent function of the wildfly-core library, which is used by WildFly and JBoss EAP to manage server deployments. The issue occurs when the library processes an unsanitized deployment name. Due to a missing containment check, an attacker with the Deployer RBAC role can use path traversal sequences to access files outside the restricted deployment directory. This can allow the attacker to delete arbitrary directories or create files with arbitrary content, leading to a full privilege escalation to the management SuperUser role.
