PYSEC-2026-562 vanna vulnerable to remote code execution caused by prompt injection

In the latest version of vanna-ai/vanna, the vanna.ask function is vulnerable to remote code execution due to prompt injection. The root cause is the lack of a sandbox when executing LLM-generated code, allowing an attacker to manipulate the code executed by the exec function in...

CVE-2026-44291

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.6 and 8.0.2, protobufjs used plain objects with inherited prototypes for internal type lookup tables used by generated encode and decode functions. If Object.prototype had already been polluted, those lookup table...

CVE-2026-44294 protobufjs: Denial of service from crafted field names in generated code

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.6 and 8.0.2, protobufjs generated JavaScript property accessors from schema-controlled field and oneof names. Certain control characters in field names were not escaped before being embedded into generated functio...

CVE-2026-44294

CVE-2026-44294 affects protobufjs. Prior to versions 7.5.6 and 8.0.2, generated JavaScript property accessors from schema-controlled field and oneof names did not escape certain control characters in field names, which could cause generated encode, decode, verify, or conversion functions to fail ...

CVE-2026-44291

CVE-2026-44291 affects protobufjs: prior to versions 7.5.6 and 8.0.2, internal type lookup tables used by generated encode/decode functions could be polluted via Object.prototype, allowing attacker-controlled inherited properties to influence protobuf type information and potentially emit attacke...

CVE-2026-44291 protobufjs: Code generation gadget after prototype pollution

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.6 and 8.0.2, protobufjs used plain objects with inherited prototypes for internal type lookup tables used by generated encode and decode functions. If Object.prototype had already been polluted, those lookup table...

protobuf.js: Denial of service from crafted field names in generated code

Summary protobufjs generated JavaScript property accessors from schema-controlled field and oneof names. Certain control characters in field names were not escaped before being embedded into generated function bodies. A crafted schema or JSON descriptor could therefore cause generated encode,...

GHSA-66FF-XGX4-VCHM protobuf.js: Code injection through bytes field defaults in generated toObject code

Summary protobufjs generated JavaScript for toObject conversion could include an unsafe expression derived from a schema-controlled bytes field default value. A crafted descriptor with a non-string default value for a bytes field could cause attacker-controlled code to be emitted into the generat...

On Fixing Insecure AI-Generated Code through Model Fine-Tuning and Prompting Strategies

The security of AI-generated code remains a major obstacle to its widespread adoption. Although code generation models achieve strong performance on functional benchmarks, their outputs frequently contain bugs and security weaknesses that undermine their trustworthiness. Prior work has explored a...

CVE-2026-42079 PPTAgent: Arbitrary Code Execution via Python eval() of LLM-Generated Code with Builtins in Scope

PPTAgent is an agentic framework for reflective PowerPoint generation. Prior to commit 418491a, PPTAgent is vulnerable to arbitrary code execution via Python eval of LLM-generated code with builtins in scope. This issue has been patched via commit 418491a...

Broken by Default: A Formal Verification Study of Security Vulnerabilities in AI-Generated Code

AI coding assistants are now used to generate production code in security-sensitive domains, yet the exploitability of their outputs remains unquantified. We address this gap with Broken by Default: a formal verification study of 3,500 code artifacts generated by seven frontier LLMs across 500...

Arbitrary Code Injection

Langflow is vulnerable to Arbitrary Code Injection. The vulnerability is due to the validation process dynamically executing LLM‑generated Python code via exec, where the validation routine runs the generated code and an attacker who can influence the model output can achieve arbitrary server‑sid...
