How to guarantee a speaker gig: Hack the system. Literally
A security researcher discovered a vulnerability in the pretalx platform that allowed him to manipulate conference speaker submissions. By exploiting this flaw, he was able to secure speaking engagements at multiple tech conferences without submitting malicious content. The vulnerability has since been patched, and the researcher emphasized responsible disclosure to affected conferences.
- ▪The vulnerability, identified as CVE-2026-41241, is a stored cross-site scripting (XSS) flaw in the pretalx platform.
- ▪The researcher, Elad Meged, used the flaw to auto-apply for 40 conferences and was accepted to present at all of them.
- ▪The flaw was patched in April 2026, and the researcher followed up with conferences to ensure responsible disclosure.
