OGNL Stricter-invocation Block List Bypass Via Java.lang.reflect Reflection Proxies

Summary OGNL's optional stricter invocation mode maintains a block list that prevents expressions from directly calling methods on dangerous classes such as "Runtime", "ProcessBuilder", and "ClassLoader". The block list filters on the declaring class of the method OGNL invokes. Because...

Authorization Bypass

goshs is vulnerable to Authorization Bypass. The vulnerability is due to inconsistent path handling, where files are opened using a cleaned path while authorization checks are performed against the raw req.URL.Path. This allows an attacker to append a trailing slash to bypass .goshs ACL-file...

GHSA-964W-F6GJ-5236 goshs has ACL Bypass & Path Traversal

Summary sendFile derives the served filename from the raw request path while opening the file from the cleaned path, so appending a trailing slash empties the derived name and defeats both the never-serve rule for the ACL file and the block list. Finding Medium: trailing-slash ACL and hidden-file...

CVE-2026-58481 Network-AI: AgentRuntime sandbox path-prefix checks allow file access outside the configured base directory

Network-AI is a TypeScript/Node.js multi-agent orchestrator. Prior to version 5.12.2, AgentRuntime promises scoped file access under a configured sandbox basePath, but its path containment checks use raw string prefix tests. A sandbox base such as /tmp/network-ai-sandbox also matches a sibling pa...
