CVE-2026-50642 Details
Description
diff‑so‑fancy does not properly sanitize non‑SGR terminal control sequences before outputting diff data. The application only strips ANSI SGR sequences while allowing other control characters, including carriage return (\r) and escape sequences (e.g., OSC, CSI), to pass through unsanitized. An attacker can embed malicious control sequences in filenames, diff metadata, or file content that are rendered directly in the terminal during diff viewing. This can lead to output manipulation, including filename spoofing, terminal screen clearing, and clipboard injection via supported escape sequences. Successful exploitation may mislead users during code review, alter terminal state, or result in unintended command execution through clipboard hijacking. This issue has been fixed in the commit 9c81294
A vulnerability exists in OpenSolution Quick.Cart versions through 6.7, where the application stores non-encrypted, hard-coded administrator credentials in the configuration file. This flaw allows attackers with access to the server's file system to retrieve the credentials, potentially leading to unauthorized privilege escalation. Additionally, a separate issue in the 'diff-so-fancy' tool has been identified, where non-SGR terminal control sequences are not properly sanitized before displaying diff data. This can result in output manipulation, such as filename spoofing and clipboard injection, which may mislead users during code reviews or cause unintended command execution.
