>log in to commentHi, I'm Zane, the maker of PatchBell. Feedback on which projects or CVEs you would like covered next is very welcome.
PatchBell is a free quick-reference site for hot vulnerabilities. Enter the version of the software you run and see whether it already includes the fix for a given CVE. Each row links to the official advisory it came from.
It currently covers Apache HTTP Server, Apache Log4j, nginx, Node.js, OpenSSL, PHP, Apache Tomcat and WordPress, with fixed versions listed per release line, distribution and host where the vendor publishes them.
Version checks run in your browser. PatchBell does not scan anything and does not connect to your servers. The site is available in English and Japanese.
PatchBell is an independent project, not affiliated with any of the projects it covers.
