CVE-2026-105080

Quick assessment

Affected
C4illin ConvertX
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 ConvertX 0.19.0 之前的版本中，converters/calibre.ts 未对 .recipe 文件进行拦截，而是直接将其传递给 Calibre 的 ebook-convert 程序处理。这会导致 .recipe 或 .downloaded_recipe 文件中的可执行代码被执行，从而引发安全风险。
