A compromised web child process could disable web security opening restrictions, leading to a new child process being spawned within the file:// context. Given a reliable exploit primitive, this new process could be exploited again leading to arbitrary file read.
Due to the Firefox GTK wrapper code’s use of text/plain for drag data and GTK treating all text/plain MIMEs containing file URLs as being dragged a website could arbitrarily read a file via a call to DataTransfer.setData.
When copying a network request from the developer tools panel as a curl command the output was not being properly sanitized and could allow arbitrary commands to be hidden within.
Per origin notification permissions were being stored in a way that didn’t take into account what browsing context the permission was granted in. This lead to the possibility of notifications to be displayed during different browsing sessions.This bug only affects Firefox for Android. Other operating systems are unaffected.
Navigations were being allowed when dragging a URL from a cross-origin iframe into the same tab which could lead to website spoofing attacks
A mishandled security check when creating a WebSocket in a WebWorker caused the Content Security Policy connect-src header to be ignored. This could lead to connections to restricted origins from inside WebWorkers.
Regular expressions used to filter out forbidden properties and values from style directives in calls to console.log weren’t accounting for external URLs. Data could then be potentially exfiltrated from the browser.
A duplicate SystemPrincipal object could be created when parsing a non-system html document via DOMParser::ParseFromSafeString. This could have lead to bypassing web security checks.
Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108 and Firefox ESR 102.6. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
