Bootstrap powers ~19% of the web. Bootstrap 2, 3, and 4 are all end-of-life — no upstream patches, and unfixed XSS CVEs stacking up (CVE-2024-6485, CVE-2025-1647, CVE-2024-6531). Only Bootstrap 5 is still supported. HeroDevs patches the rest. #Bootstrap #CyberSecurity #EOL #OpenSource
Post summary
The post warns that Bootstrap 2‑4 are EOL with unfixed XSS CVEs and that HeroDevs provides patches, while only Bootstrap 5 remains supported.
