FileRun: When Your File Manager Runs Your Files
OS Command Injection in FileRun's thumbnail generation - authenticated (CVSS v4 8.7) or via public 'file request' weblinks (CVSS v4 9.2). The extractors wrap file paths in double quotes and pass them to exec(), but the filename sanitizer allows $(){}` - enough for command substitution. The weblink path uploads a malicious filename via anonymous upload, then self-triggers thumbnail generation through the public listing.

Aimy Captcha-Less Form Guard: The Anti-Bot Plugin That Hands Bots the Keys
An unauthenticated PHP object injection in Aimy Captcha-Less Form Guard for Joomla, where a repeating-key XOR published alongside its own ciphertext turns every protected form into an unserialize() sink and, on Joomla 3.9 through 5.2.1, into remote code execution.
Monsta FTP: An SSRF Blocklist That Forgot IPv6 Exists
An unauthenticated SSRF in Monsta FTP 2.14.4. The product ships a real SSRF blocklist that correctly blocks 127.0.0.1, 169.254.169.254 and RFC1918, then forgets that ::ffff:169.254.169.254 is the exact same host. One missing normalization, both gates bypassed, and a static AAAA record is all it takes.
NVIDIA GEN3C: Unauthenticated RCE via Pickle Deserialization in Inference API
A critical unauthenticated RCE vulnerability in NVIDIA's GEN3C project. Two FastAPI inference endpoints deserialize raw HTTP POST bodies with pickle.loads() without any authentication, giving instant code execution to anyone with network access.
FOSSBilling: One Missing throw - From Auth Bypass to Unauthenticated RCE
A missing throw keyword in FOSSBilling's API router exposes the entire admin surface to unauthenticated attackers. Combined with an unsandboxed Twig SSTI that leaks the full DI container, this leads to arbitrary SQL execution, admin takeover, and unauthenticated RCE via malicious extension installation.
CVE-2026-29514: NetBox Jinja2 Sandbox Bypass to RCE via RenderTemplateMixin environment_params
A Jinja2 sandbox bypass in NetBox allows low-privilege users to achieve remote code execution via the RenderTemplateMixin environment_params finalize parameter, affecting both ExportTemplate and ConfigTemplate.
Unauthenticated RCE in OpenCATS via Installer Config Injection
Unauthenticated remote code execution in OpenCATS through unsanitized input in the installer AJAX endpoint, allowing PHP code injection into config.php.
