CWE ID 416


CVE-2023-48706 is a heap-use-after-free vulnerability found in Vim, a UNIX editor. The vulnerability affects versions prior to 9.0.2121. When executing a :s command for the first time and using a sub-replace-special atom inside the substitution part, it is possible that the recursive :s call causes freeing of memory which may later be accessed by the initial :s command. The user must intentionally execute the payload, and it seems to work reliably only for the first :s command. The vulnerability may lead to a crash of Vim but has a low base severity and base score. Version 9.0.2121 contains a fix for this issue.
