CVE-2026-95519— Rpm: code execution via macro expansion of manifest entries in `rpmgi` (`-q -p` / verify manifest flows)

Quick assessment

Affected
Red Hat Red Hat Enterprise Linux 10
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 rpm 中发现了一个漏洞。攻击者可以构造一个恶意的清单文件（manifest file），当用户使用 或类似的清单处理流程处理该文件时，会导致任意代码执行。该问题的根源在于：清单条目在打开之前会被意外地进行宏展开，从而使得嵌入的 shell 命令得以在 rpm 进程的权限上下文中执行。成功利用此漏洞可能导致受影响账户的机密性、完整性和可用性遭到完全破坏。

Vulnerability Title
Rpm: code execution via macro expansion of manifest entries in `rpmgi` (`-q -p` / verify manifest flows)
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in rpm. An attacker can supply a crafted manifest file that, when processed by a user or automation using `rpm -q -p` or similar manifest-processing flows, leads to arbitrary code execution. This occurs because manifest entries are unexpectedly macro-expanded before being opened, allowing embedded shell commands to run with the privileges of the `rpm` process. Successful exploitation can lead to a full compromise of confidentiality, integrity, and availability for the affected account.
