CVE-2026-48780 (GCVE-0-2026-48780)

Vulnerability from cvelistv5 – Published: 2026-06-16 14:10 – Updated: 2026-06-17 13:49

Title
Forem vulnerable to bypass of email address domain restrictions
Summary
Forem is open source software for building communities. Prior to commit a2ab6d4, a maliciously crafted email address could allow an attacker to bypass domain allowlist or denylist restrictions and gain access to invite-only forem deployments. The issue is patched as of `a2ab6d4`. As a workaround, some SMTP servers and email delivery providers may drop or refuse to send maliciously crafted email addresses.
