GHSA-7WQV-XJF3-X35V parse-server: Stored XSS via trailing-dot filename bypassing file upload extension blocklist

Impact The default file upload extension blocklist can be bypassed by appending a trailing dot to a filename whose extension would otherwise be blocked e.g. poc.svg.. The trailing dot causes the extension parser to extract an empty string, which short-circuits the blocklist check, and the...

GHSA-J99Q-93C9-H869 MCPVault: PathFilter restricted-directory deny-list bypass via case and trailing dot/space equivalence

On case-insensitive filesystems macOS, Windows, PathFilter compiled its deny-list patterns case-sensitively and matched the path verbatim, so names like .Git/config, .GIT/config, or .oBsIdIaN/secrets.md slipped past the .git/.obsidian/nodemodules restriction while the OS opened the real file. On...
