Code Injection

SimpleEval is vulnerable to code injection. The vulnerability is due to objects leaking dangerous modules through to direct access inside the sandbox, where dangerous functions or modules could be accessed by passing them as callbacks to other safe functions to call...

Impact If the objects passed in as names to SimpleEval have modules or other disallowed / dangerous objects available as attrs. Additionally, dangerous functions or modules could be accessed by passing them as callbacks to other safe functions to call. Examples found by @ByamB4: Any module where...

Improperly Controlled Modification of Dynamically-Determined Object Attributes

Overview simpleeval is an A simple, safe single expression evaluator library. Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes in the evaluation when objects passed as names contain modules or other disallowed objec...
