The force-reset-password endpoint permits anonymous requests and fails to verify the existing password or a reset token when resetting system administrator accounts. An unauthenticated attacker can supply a target administrator username and a new password to reset the account, resulting in full administrative compromise of the SmarterMail instance. NOTE: SmarterMail system administrator privileges grant the ability to execute operating system commands via built-in management functionality, effectively providing administrative (SYSTEM or root) access on the underlying host.\n\n## Affected\n\n- `smartermail < 100.0.9511`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `smartermail 100.0.9511`","depth":"hadal","depthScore":100,"depthScoreParts":{"impact":53.9,"likelihood":19.3,"exploitation":25,"ransomware":5},"changes":[{"seq":5020,"id":"CVE-2026-23760","ts":1788887229011,"field":"exploit_available","old":"false","new":"true"},{"seq":3903,"id":"CVE-2026-23760","ts":1788886360074,"field":"exploit_available","old":"true","new":"false"},{"seq":2725,"id":"CVE-2026-23760","ts":1788883025823,"field":"exploit_available","old":"false","new":"true"},{"seq":1754,"id":"CVE-2026-23760","ts":1788882429846,"field":"exploit_available","old":"true","new":"false"},{"seq":860,"id":"CVE-2026-23760","ts":1788881862862,"field":"exploit_available","old":"false","new":"true"}]}
