### Summary According to the [docs](https://github.com/shubhamjain/svg-loader/tree/main#2-enable-javascript), svg-loader will strip all JS code before injecting the SVG file for security reasons but the input sanitization logic is not sufficient and can be trivially bypassed. This allows an attacker to craft a malicious SVG which can result in XSS. ### Details When trying to sanitize the svg the lib [removes event attributes](https://github.com/shubhamjain/svg-loader/blob/main/svg-loader.js#L125-L128) such as `onmouseover`, `onclick` but the list of events is not exhaustive. Here's a list of events not removed by svg-loader. `onafterscriptexecute, onbeforecopy, onbeforecut, onbeforescriptexecute, onbeforetoggle, onbegin, onbounce, onend, onfinish, onfocusin, onfocusout, onmousewheel, onpointerrawupdate, onrepeat, onsearch, onshow, onstart, ontoggle(popover), ontouchend, ontouchmove, ontouchstart` As you can see in the POC we can use `onbegin` in `animate` tag to execute JS code with...

### Impact OpenZeppelin Contracts is a library for secure smart contract development. Starting in version 4.0.0 and prior to version 4.9.3, contracts using `ERC2771Context` along with a custom trusted forwarder may see `_msgSender` return `address(0)` in calls that originate from the forwarder with calldata shorter than 20 bytes. This combination of circumstances does not appear to be common, in particular it is not the case for `MinimalForwarder` from OpenZeppelin Contracts, or any deployed forwarder the team is aware of, given that the signer address is appended to all calls that originate from these forwarders. ### Patches The problem has been patched in v4.9.3.

Threat actors are increasingly using a phishing-as-a-service (PhaaS) toolkit dubbed EvilProxy to pull off account takeover attacks aimed at high-ranking executives at prominent companies. According to Proofpoint, an ongoing hybrid campaign has leveraged the service to target thousands of Microsoft 365 user accounts, sending approximately 120,000 phishing emails to hundreds of organizations
## Impact The `import-in-the-middle` loader used by `@opentelemetry/instrumentation` works by generating a wrapper module on the fly. The wrapper uses the module specifier to load the original module and add some wrapping code. It allows for remote code execution in cases where an application passes user-supplied input directly to an `import()` function. ## Patches This vulnerability has been patched in `@opentelemetry/instrumentation` version `0.41.2` ## Workarounds - Do not pass any user-supplied input to `import()`. Instead, verify it against a set of allowed values. - If using `@opentelemetry/instrumentation` with support for EcmaScript Modules is not needed, ensure that none of the following options are set (either via command-line or the `NODE_OPTIONS` environment variable): ``` --experimental-loader=@opentelemetry/instrumentation/hook.mjs --experimental-loader @opentelemetry/instrumentation/hook.mjs --loader=import-in-the-middle/hook.mjs --loader import-in-the-middle/hook.m...
### Impact This is a hole in the confinement of guest applications under SES that may manifest as either the ability to exfiltrate information or execute arbitrary code depending on the configuration and implementation of the surrounding host. Guest program running inside a Compartment with as few as no endowments can gain access to the surrounding host’s dynamic import by using dynamic import after the spread operator, like `{...import(arbitraryModuleSpecifier)}`. On the web or in web extensions, a Content-Security-Policy following ordinary best practices likely mitigates both the risk of exfiltration and execution of arbitrary code, at least limiting the modules that the attacker can import to those that are already part of the application. However, without a Content-Security-Policy, dynamic import can be used to issue HTTP requests for either communication through the URL or for the execution of code reachable from that origin. Within an XS worker, an attacker can use the host’s...
