CVE-2026-107802
Description
SumatraPDF is a multi-format reader for Windows. In 3.6.1 and earlier, src/SelectionTranslate.cpp embeds selected or pasted translation text in quoted Windows command lines using incomplete quote-only escaping. The affected BuildGrokTranslateCmdLineTemp(), BuildClaudeTranslateCmdLineTemp(), and BuildCodexTranslateCmdLineTemp() functions can allow attacker-controlled text to inject model, working-directory, approval, or sandbox-bypass flags when the corresponding agentic CLI backend is installed and used. No broader impact is claimed beyond the advisory-supported conditions. No fixed version is available as of this review.
