Mozilla Firefox and 2 others: Unrestricted Upload of File with Dangerous Type
CVE-2022-34482 is fixed in 5 products on 2 platforms, first by Mozilla Firefox ESR (en-US) 102.0, released June 23, 2022. It is not reported as exploited. Patch Radar priority: High.
An attacker who could have convinced a user to drag and drop an image to a filesystem could have manipulated the resulting filename to contain an executable extension, and by extension potentially tricked the user into executing malicious code. While very similar, this is a separate issue from CVE-2022-34483. This vulnerability affects Firefox < 102.
