The vulnerability is particularly dangerous because log4j is used in many Java applications and is easy to exploit. The source mentions that patches were released to fix the issue, though it also notes that bypasses to those patches were discovered, leading to additional patches.
Solution / Mitigation
Patches were released to address the vulnerability. The source notes that when bypasses to initial patches were discovered, additional patches were subsequently released.
