kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...

PraisonAI: Origin-validation bypass (startswith prefix match) enables unauthenticated cross-site request forgery against the PraisonAI MCP HTTP server

Summary The PraisonAI MCP server exposes an HTTP-stream transport praisonai mcp serve --transport http-stream that binds to localhost and, by default, has no API key. Its only access control for browser-originated requests is an Origin allowlist, which the code implements as required by the MCP...

CVE-2026-55529

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, the MCP HTTP Stream validateorigin method accepts requestorigin.startswithallowed, so the attacker-controlled localhost.evil.example HTTP origin matches the localhost allowlist. Without an API key, a malicious webpage can submit...

CVE-2026-79774 Winter CMS before 1.2.13 Twig Sandbox Escape via SecurityPolicy

Winter CMS versions before 1.2.13 contain an incomplete fix for a Twig sandbox escape vulnerability in System\Twig\SecurityPolicy that allows authenticated backend users with template-editing permissions to bypass sandbox restrictions. Attackers can exploit method forwarding through Eloquent...

CVE-2026-79772

Nokogiri versions before 1.19.1 (a widely used Ruby XML library) contain an unchecked return value in the canonicalize method. The method calls xmlC14NExecute but fails to check its return value, returning an empty string on failure instead of raising an exception. This allows an attacker to bypa...

CVE-2026-79771

Nokogiri versions before 1.19.3 are affected by a memory leak in the XSLT Stylesheet transform method. The root cause is heap allocations leaking when Ruby strings containing null bytes are passed as transform parameters. An unauthenticated, network-based attacker can trigger this by supplying cr...
