CVE-2026-55585

QWED is open-source AI verification infrastructure for deterministic verification of LLM outputs, tool calls, code, schemas, and agent state before production execution. Prior to 5.1.2, the qwed package passes caller-controlled math expressions directly to SymPy parseexpr without restricted...

qwed Vulnerable to Authenticated Remote Code Execution via Unsafe SymPy `parse_expr()`

Summary The qwed package version 5.1.1 passes attacker-controlled input directly to SymPy's parseexpr function without a restricted namespace. Because parseexpr internally calls Python's eval, any authenticated tenant can execute arbitrary Python code inside the API server process. The attack...

CVE-2026-55585

QWED (open-source AI verification infrastructure) prior to version 5.1.2 is vulnerable to authenticated Remote Code Execution . Caller-controlled math expressions are passed directly to SymPy parse_expr() without restricted global_dict/local_dict namespaces, effectively allowing Python eval() to ...

CVE-2026-55546

QWED-MCP is a deterministic verification gateway for MCP. Prior to 0.2.1, verifymathexpression in src/qwedmcp/engines/mathengine.py passes attacker-controlled expression and claimedresult strings directly to SymPy's parseexpr after only normalizing caret syntax to Python exponent syntax, without...

qwed-mcp has Unsafe SymPy `parse_expr()` Remote Code Execution via Unsanitized Math Expression Input

Summary verifymathexpression in qwed-mcp v0.2.0 passes attacker-controlled strings directly to SymPy's parseexpr without restricting globaldict or validating the expression's AST. Because parseexpr internally calls eval and Python automatically injects the current module's builtins when no explic...
