SCA: security update for qwed (GHSA-q27q-98j4-9pfv)

high Tenable Self-Hosted Container Security Plugin ID 446265

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 parse_expr() without restricted global_dict and
 local_dict namespaces, allowing Python eval() to resolve builtins and execute arbitrary Python code in the
 API server process. In src/qwed_new/api/main.py, POST /verify/math is protected by get_current_tenant but
 accepts any valid tenant API key, reads the expression field, applies only a cosmetic re.sub(r'(\d)(()',
 r'\1*\2', expression) normalization, and passes the result to parse_expr(). In src/qwed_new/core/batch.py,
 POST /verify/batch sends math items through batch_service.create_job(), stores item.query verbatim, and
 _verify_item() passes VerificationType.MATH input to parse_expr() without sanitization. The default-
 enabled POST /auth/signup endpoint allows anyone to create a standard tenant account, POST /auth/api-keys
 issues an x-api-key, and either vulnerable path can then be used to read or write files, modify data,
 execute operating system commands, terminate the service, and compromise other tenants in a shared
 deployment. This issue is fixed in version 5.1.2. (CVE-2026-55585)

Solution

Update the qwed library and its related packages to version 5.1.2 or later.
