Mozilla has released security updates for multiple products to address zero-day vulnerabilities exploited during the Pwn2Own Vancouver 2022 hacking contest.

If exploited, the two critical flaws can let attackers gain JavaScript code execution on mobile and desktop devices running vulnerable versions of Firefox, Firefox ESR, Firefox for Android, and Thunderbird.

Manfred Paul earned $100,000 and 10 Master of Pwn points after demoing prototype pollution and improper input validation bugs on the first day of Pwn2Own.

Mozilla patched these vulnerabilities two days after they were exploited and reported at the Pwn2Own hacking contest by Manfred Paul.

Vendors don't usually hurry to release patches after Pwn2Own since they have 90 days to push security fixes until Trend Micro's Zero Day Initiative publicly discloses them.

Pwn2Own 2022 Vancouver ended on May 20 after 17 competitors earned $1,155,000 for zero-day exploits and exploit chains demonstrated over three days after 21 attempts.
