Low risk4th percentile - higher than 4% of all known CVEs
Summary
In Vim prior to version 9.2.0699, the Python omni-completion function executes reconstructed function and class definitions from the current buffer using exec(). During source reconstruction, each scope's docstring is inserted verbatim between triple quotes without escaping, allowing a malicious buffer to break out of the triple-quoted literal and execute attacker-controlled Python code during omni-completion.
Risk Assessment
An attacker can inject and execute arbitrary Python code in the context of the Vim editor, potentially leading to system compromise or data theft.
Recommendation
Immediately update Vim to version 9.2.0699 or later, which contains a fix for this vulnerability.

YesWiki prior to version 4.6.6 has a vulnerability in the {{erasespamedcomments}} wiki action that deletes arbitrary wiki pages without authorization based on a suppr[] array from POST. The default ACL model allows any user with write access to delete pages, including the front page and admin pages.

Improper neutralization of CRLF sequences in IXON VPN Client before version 1.4.7 allows an attacker to execute commands as root or SYSTEM. Configuration values accepted by the local service are written to a file later consumed by a privileged subprocess, without line-ending sequences being neutralized, which allows additional directives to be introduced into that file. The configuration interface accepts changes without authenticating or verifying the origin of the requester. The injected configuration persists on disk across restarts of the client and the operating system, and the VPN connection continues to function normally, so there is no behavioral change visible to the user.

Original NVD description (English source)
Vim is an open source, command line text editor. Prior to 9.2.0699, Vim's Python omni-completion (runtime/autoload/python3complete.vim and the legacy pythoncomplete.vim) executes reconstructed function and class definitions from the current buffer with exec() as part of populating the completion dictionary. When reconstructing that source, each scope's docstring is inserted verbatim between triple quotes with no escaping, so a hostile buffer can break out of the triple-quoted literal and execute attacker-controlled Python during omni-completion. This vulnerability is fixed in 9.2.0699.
