CVE-2026-4963

A weakness has been identified in huggingface smolagents 1.25.0.dev0. This affects the function evaluateaugassign/evaluatecall/evaluatewith of the file src/smolagents/localpythonexecutor.py of the component Incomplete Fix CVE-2025-9959. This manipulation causes code injection. It is possible to...

Out-of-bounds Write

Vyper is vulnerable to Out-of-bounds Write. The vulnerability is due to improper bounds validation due to the caching of the target location in an AugAssign statement, which prevents re-evaluating the bounds check when modifying a DynArray...

CVE-2025-27105

A flaw was found in Vyper, a Pythonic Smart Contract Language for the EVM. This vulnerability allows out-of-bounds writes via improper bounds checking when modifying a DynArray using an augmented assignment AugAssign. Mitigation Mitigation for this issue is either not available or the currently...

AugAssign evaluation order causing OOB write within the object in Vyper

Vyper handles AugAssign statements by first caching the target location to avoid double evaluation. However, in the case when target is an access to a DynArray and the rhs modifies the array, the cached target will evaluate first, and the bounds check will not be re-evaluated during the write...

CVE-2025-27105

The Vyper smart contract language for the EVM is vulnerable to an Out-of-bounds Write (CWE-787). The issue stems from how the language handles AugAssign statements by caching the target location to avoid double evaluation. Specifically, when the target is an access to a DynArray and the right-han...
