> When it was first revealed in early December 2021, the Log4Shell bug was described as one of the most severe security vulnerabilities ever. > The Apache Software Foundation, which maintains the open-source tool, quickly released a patch... Apache horribly mismanaged this and did not release a patch until it was already widely known and being exploited in the wild. They also messed up and had to release several subsequent patches to actually fix the vulnerability. This greatly contributed to "[the] mad scramble to plug the gaps". You can watch the chaos unfold by reading through the GitHub PR. Remember, this was disclosed to Apache in November. https://github.com/apache/logging-log4j2/pull/608#issuecomme...
In Log4Shell Still Has Sting in the Tail
Ha! Well, there's a lot. On major strand is more work like this to make it easy for the community to collaborate. I expect we'll make a lot of iterative improvements to the database over the next few months, aimed at making it easier to contribute to, maintain and use. We need to improve our APIs for this data, for example (currently only available via GraphQL). Another big one that we're starting to think about is the security vulnerability disclosure process. Our goal there is to support maintainers as much as possible, and there's more we can do. Recent articles on loguru, beg bounties, and the way log4j initially reached public attention all point to problems GitHub can and should help with. In the next 12 months we'd like to give maintainers the option to receive vulnerability disclosures privately on GitHub, and for us to be able to

support them through that process. (GitHub already does a bit here - through maintainer security advisories we issued about 30% of the CVEs in the JavaScript ecosystem last year, for example. But we can and will do more.) Loguru CVE article: https://tomforb.es/cve-2022-0329-and-the-problems-with-autom...
