CVE-2026-33686
HighSummary
Sharp to framework do zarządzania treścią stworzony dla Laravel jako pakiet. Wersje przed 9.20.0 mają podatność na traversowanie ścieżek w klasie FileUtil, ponieważ aplikacja nieprawidłowo sanitizuje rozszerzenia plików, co pozwala na wprowadzenie separatorów ścieżek do warstwy przechowywania.
Risk Assessment
Organizacja może być narażona na ataki, które wykorzystują tę podatność do uzyskania dostępu do nieautoryzowanych plików w systemie plików. Może to prowadzić do ujawnienia wrażliwych danych lub manipulacji plikami.
Recommendation
Zaleca się aktualizację do wersji 9.20.0 lub nowszej, aby załatać tę podatność poprzez poprawne sanitizowanie rozszerzeń plików.

Bifrost registers MCP clients through its management API, where a stdio client is a command plus args that is started immediately upon client addition, with no MCP handshake required. Authentication is disabled by default (governance.auth_config.is_enabled=false), meaning every caller is treated as a local admin. A single unauthenticated POST /api/mcp/client is enough to run a program as the Bifrost process user (appuser on the official image).

- CVE-2026-85192Critical
The Joomla Conditional Content extension (regularlabs.com) in versions < 8.0.0 allows authenticated, privileged remote code execution. Conditional Content Pro accepts inline PHP Condition Rules in article syntax, and in affected versions the PHP is passed to the Conditions evaluator without checking who authored the article. Joomla's normal Author text filter preserves the syntax, so publishing the article causes the code to run as the web-server process.

Original NVD description (English source)
Sharp is a content management framework built for Laravel as a package. Versions prior to 9.20.0 have a path traversal vulnerability in the FileUtil class. The application fails to sanitize file extensions properly, allowing path separators to be passed into the storage layer. In `src/Utils/FileUtil.php`, the `FileUtil::explodeExtension()` function extracts a file's extension by splitting the filename at the last dot. This issue has been patched in version 9.20.0 by properly sanitizing the extension using `pathinfo(PATHINFO_EXTENSION)` instead of `strrpos()`, alongside applying strict regex replacements to both the base name and the extension.
