rumenx/php-sitemap is vulnerable to Path Traversal
20
Low Risk
This Affects:
rumenx/php-sitemapTL;DR
Sitemap::store() concatenates the output directory with the caller supplied $filename without removing path separators or .. segments before writing the file. Untrusted filename values can escape the intended output directory and write sitemap output to arbitrary filesystem locations writable by the PHP process. The fix rejects filenames containing NUL bytes, path separators, or ./.. and reduces the value to a basename before building the path.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you pass externally influenced input into the $filename argument of store().
