Title
SmarterTools SmarterMail < Build 9560 Server Local File Inclusion via the /api/v1/report/summary/{type} API
Summary
SmarterTools SmarterMail builds prior to 9560 contain a local file inclusion vulnerability in the /api/v1/report/summary/{type} API endpoint that allows authenticated users to read arbitrary .json files on the system. Attackers can exploit this vulnerability combined with weak encryption algorithms and hardcoded keys to decrypt and access stored passwords and 2FA secrets for all users.

CVE-2026-40514 (GCVE-0-2026-40514)

Vulnerability from nvd – Published: 2026-04-27 14:21 – Updated: 2026-04-27 20:11

Title
SmarterTools SmarterMail < Build 9610 Cryptographic Weakness via Weak RNG
Summary
SmarterTools SmarterMail builds prior to 9610 contain a cryptographic weakness in the file and email sharing endpoints that use DES-CBC encryption with keys and initialization vectors derived from System.Random seeded with insufficient entropy, reducing the seed space to approximately 19,000 possible values. An unauthenticated attacker can use the attachment download endpoint as an oracle to determine the seed in use and derive encryption keys and initialization vectors to forge sharing tokens for arbitrary emails, attachments, or file storage contents without prior access to the targeted content.
Severity ?

Title
SmarterTools SmarterMail < Build 9560 Server Local File Inclusion via the /api/v1/report/summary/{type} API
Summary
SmarterTools SmarterMail builds prior to 9560 contain a local file inclusion vulnerability in the /api/v1/report/summary/{type} API endpoint that allows authenticated users to read arbitrary .json files on the system. Attackers can exploit this vulnerability combined with weak encryption algorithms and hardcoded keys to decrypt and access stored passwords and 2FA secrets for all users.

Title
SmarterTools SmarterMail < Build 9610 Cryptographic Weakness via Weak RNG
Summary
SmarterTools SmarterMail builds prior to 9610 contain a cryptographic weakness in the file and email sharing endpoints that use DES-CBC encryption with keys and initialization vectors derived from System.Random seeded with insufficient entropy, reducing the seed space to approximately 19,000 possible values. An unauthenticated attacker can use the attachment download endpoint as an oracle to determine the seed in use and derive encryption keys and initialization vectors to forge sharing tokens for arbitrary emails, attachments, or file storage contents without prior access to the targeted content.
