CVE-2026-112900— Pillow: Argument Injection in Ghostscript call, potentially leading into RCE
Quick assessment
Affected
python-pillow Pillow
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.
Pillow 是一个 Python 图像处理库。在 2.6.0 至 13.0.0 版本中，当 Pillow 调用 Ghostscript 处理 EPS 输入时，存在参数注入漏洞。 在 参数后直接传递由调用者控制的输入文件名，而未将其转换为安全的路径；因此，若文件名以连字符（ ）开头，Ghostscript 会将其误解析为自身的命令行选项。攻击者若能控制文件名，即可注入任意的 Ghostscript 参数。若要实现任意命令执行，则需满足两个条件：一是使用以 开头的参数文件（argument-file）文件名，二是能够

Vulnerability Title
Pillow: Argument Injection in Ghostscript call, potentially leading into RCE
Source: CVE Program / CVE List V5
Vulnerability Description
Pillow is a Python imaging library. From 2.6.0 until 13.0.0, Pillow is vulnerable to argument injection when invoking Ghostscript for EPS input. EpsImagePlugin.Ghostscript passes a caller-controlled input filename after -f without converting it to a safe absolute path, so a name beginning with a hyphen can be interpreted as a Ghostscript option. An attacker who controls the filename can inject Ghostscript arguments. Arbitrary command execution specifically requires a leading @ argument-file filename and control of the referenced text file containing additional Ghostscript arguments; the reported chain reproduces with the default -dSAFER invocation. This issue is fixed in version 13.0.0.
