Note: Versions mentioned in the description apply only to the upstream firefox-esr package and not the firefox-esr package as distributed by Alpine. See How to fix? for Alpine:3.19 relevant fixed versions and status.

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.
