CVE-2025-67731
HighSummary
Servify Express to pakiet Node.js do uruchamiania serwera Express, który przed wersją 1.2 nie miał limitu rozmiaru dla express.json(). To umożliwia atakującym wysyłanie bardzo dużych ciał żądań, co może prowadzić do nadmiernego zużycia pamięci, pogorszenia wydajności lub awarii procesów, skutkując atakiem typu Denial of Service (DoS).
Risk Assessment
Organizacje korzystające z aplikacji używających parsera JSON bez limitów i wystawionych na niezaufanych klientów są narażone na ataki DoS, co może prowadzić do przerw w dostępności usług.
Recommendation
Zaleca się aktualizację do wersji 1.2 lub dodanie opcji limitu do parsera JSON, wprowadzenie limitów szybkości na poziomie aplikacji lub reverse proxy oraz odrzucanie wyjątkowo dużych żądań przed ich parsowaniem.

- CVE-2026-88857Critical
In the OrdaSoft Joomla Gallery extension for Joomla versions below 6.2.7, an authenticated privileged remote code execution vulnerability was found. The saveWatermark() function copies an uploaded file to a web-accessible directory using the client-supplied filename exactly as sent, with no extension check, content check, or filename sanitization. An authenticated core.manage user could upload a .php file disguised with an image Content-Type header and execute it directly by requesting the resulting path.
- CVE-2026-88856Critical
In the OrdaSoft Joomla Gallery extension for Joomla versions below 6.2.7, an authenticated privileged remote code execution vulnerability was found. The updateOSGallery() function, reached via task=update_osgallery, reads a JSON request body and calls the value of a method field as a live PHP function, passing the value of a package field as its single argument, with no allow-list or is_callable() check. Any function name compatible with a single argument is directly reachable, including system, exec, shell_exec, and passthru.
Original NVD description (English source)
Servify Express is a Node.js package to start an Express server and log the port it's running on. Prior to 1.2, the Express server used express.json() without a size limit, which could allow attackers to send extremely large request bodies. This can cause excessive memory usage, degraded performance, or process crashes, resulting in a Denial of Service (DoS). Any application using the JSON parser without limits and exposed to untrusted clients is affected. The issue is not a flaw in Express itself, but in configuration. This issue is fixed in version 1.2. To work around, consider adding a limit option to the JSON parser, rate limiting at the application or reverse-proxy level, rejecting unusually large requests before parsing, or using a reverse proxy (such as NGINX) to enforce maximum request body sizes.
