CVE-2026-92298

EspoCRM through 10.0.8 uses PHP's rand() function to generate tokens for lead-capture opt-in, event invitation, and campaign URLs instead of a cryptographically secure generator. Remote unauthenticated attackers can guess these roughly 31-bit tokens to confirm opt-ins, accept or decline event invitations on behalf of other contacts, and access event details.
