Red Hat Security Advisory: OpenShift Container Platform 4.21.26 bug fix and security update

Important

A flaw was found in the shell-quote component. The quote() function did not properly validate object-token inputs, allowing line terminators to pass unescaped into the output. A remote attacker could exploit this vulnerability by providing specially crafted input, which a POSIX shell would interpret as a command separator. This could lead to command injection, enabling the attacker to execute arbitrary code on the system.

CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

A flaw was found in form-data, a library for creating readable multipart/form-data streams. A remote attacker can exploit this vulnerability by injecting carriage return (CR), line feed (LF), or double-quote (") characters into the `field` argument of `FormData#append` or the `filename` option. This allows the attacker to inject additional headers or smuggle entire additional multipart parts into requests, potentially enabling them to add or override form fields and compromise data integrity.

CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')
