CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2023-23602 – Mozilla: Content Security Policy wasn't being correctly applied to WebSockets in WebWorkers
https://notcve.org/view.php?id=CVE-2023-23602
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. This vulnerability affects Firefox < 109, Thunderbird < 102.7, and Firefox ESR < 102.7. The Mozilla Foundation Security Advisory describes this flaw as: A mishandled security check when creating a WebSocket in a WebWorker caused the Content Security Policy connect-src header to be ignored.

https://notcve.org/view.php?id=CVE-2023-23603
Regular expressions used to filter out forbidden properties and values from style directives in calls to <code>console.log</code> weren't accounting for external URLs. Data could then be potentially exfiltrated from the browser. This vulnerability affects Firefox < 109, Thunderbird < 102.7, and Firefox ESR < 102.7.

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.

The <code>ms-msdt</code>, <code>search</code>, and <code>search-ms</code> protocols deliver content to Microsoft applications, bypassing the browser, when a user accepts a prompt. These applications have had known vulnerabilities, exploited in the wild (although we know of none exploited through Thunderbird), so in this release Thunderbird has blocked these protocols from prompting the user to open them.<br>*This bug only affects Thunderbird on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. • https://bugzilla.mozilla.org/show_bug.cgi?id=1773717 https://www.mozilla.org/security/advisories/mfsa2022-24 https://www.mozilla.org/security/advisories/mfsa2022-25 https://www.mozilla.org/security/advisories/mfsa2022-26 •
