:warning: Security fixes
- Fix an XSS vulnerability in various confirmation prompts commonly used when deleting things. Exploitation requires someone with at least submission privileges (such as a speaker) and then rely on someone else to attempt to delete this content. However, considering that event organizers may indeed delete suspicious-looking content when encountering it, there is a non-negligible risk of such an attack to succeed. Because of this it is strongly recommended to upgrade as soon as possible (5862, CVE-2023-37901, GHSA-fmqq-25x9-c6hm)
