WordPress developers on Thursday announced the availability of version 5.2.3, a maintenance and security release that includes 29 fixes and enhancements, along with several security patches.
As far as security is concerned, WordPress 5.2.3 mostly patches cross-site scripting (XSS) vulnerabilities. Two of them have been reported by Simon Scannell of RIPS Technologies, including XSS bugs in post previews and in stored comments.
