CVE-2022-29247
Electron is a framework for writing cross-platform desktop applications using JavaScript (JS), HTML, and CSS. A vulnerability in versions prior to 18.0.0-beta.6, 17.2.0, 16.2.6, and 15.5.5 allows a renderer with JS execution to obtain access to a new renderer process with `nodeIntegrationInSubFrames` enabled which in turn allows effective access to `ipcRenderer`. The `nodeIntegrationInSubFrames` option does not implicitly grant Node.js access. Rather, it depends on the existing sandbox setting. If an application is sandboxed, then `nodeIntegrationInSubFrames` just gives access to the sandboxed renderer APIs, which include `ipcRenderer`. If the application then additionally exposes IPC messages without IPC `senderFrame` validation that perform privileged actions or return confidential data this access to `ipcRenderer` can in turn compromise your application / user even with the sandbox enabled. Electron versions 18.0.0-beta.6, 17.2.0, 16.2.6, and 15.5.5 contain a fix for this issue. As a workaround, ensure that all IPC message handlers appropriately validate `senderFrame`.

trunk.cocoapods.org is the authentication server for the CoacoaPods dependency manager. A vulnerability affected older pods which migrated from the pre-2014 pull request workflow to trunk. If the pods had never been claimed then it was still possible to do so. It was also possible to have all owners removed from a pod, and that made the pod available for the same claiming system. This was patched server-side in commit 71be5440906b6bdfbc0bcc7f8a9fec33367ea0f4 in September 2023.
