From 645ed6597d1ea896c712cd7ddbb6edee79577e9a Mon Sep 17 00:00:00 2001 From: pyllyukko Date: Thu, 19 Mar 2026 19:58:05 +0000 Subject: [PATCH] patch 9.2.0202: [security]: command injection via newline in glob() Problem: The glob() function on Unix-like systems does not escape newline characters when expanding wildcards. A maliciously crafted string containing '\n' can be used as a command separator to execute arbitrary shell commands via mch_expand_wildcards(). This depends on the user's 'shell' setting. Solution: Add the newline character ('\n') to the SHELL_SPECIAL definition to ensure it is properly escaped before being passed to the shell (pyllyukko). closes: #19746 Github Advisory: https://github.com/vim/vim/security/advisories/GHSA-w5jw-f54h-x46c Signed-off-by: pyllyukko Signed-off-by: Christian Brabandt --- src/os_unix.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/os_unix.c b/src/os_unix.c index 03f7649090c96..91bfd63d0dcb2 100644 --- a/src/os_unix.c +++ b/src/os_unix.c @@ -6772,7 +6772,7 @@ mch_expand_wildcards( # define SEEK_END 2 #endif -#define SHELL_SPECIAL (char_u *)"\t \"&'$;<>()\\|" +#define SHELL_SPECIAL (char_u *)"\t \"&'$;<>()\\|\n" int mch_expand_wildcards(
