When a user copies a request containing crafted characters and pastes it into a terminal or command prompt on Windows, the shell may interpret them as executable code, leading to unintended command execution. This flaw affords an attacker the ability to trigger arbitrary local code execution, effectively compromising the user's system whenever they interact with the sanitized cURL string.

However, the EPSS score is below 1\u202f%, indicating a very low probability of widespread exploitation in the near term. The flaw is not listed in CISA\u2019s KEV catalog. It requires a user to copy the malicious cURL line and paste it into a Windows command shell, which is a user\u2011assisted attack vector. Successful exploitation would give an attacker local privileges on the victim machine and the ability to execute arbitrary commands."}}}}, "created": "2025-10-20T15:49:33.497133+00:00", "updated": "2026-04-20T19:15:15.051210+00:00", "vendors": ["microsoft", "microsoft$PRODUCT$windows", "mozilla", "mozilla$PRODUCT$firefox", "mozilla$PRODUCT$firefox_esr", "mozilla$PRODUCT$thunderbird"]}
