CVE-2026-74868

SiYuan versions before 3.7.4 contain an unthrottled brute-force vulnerability in the Publish Service Basic Auth implementation PublishServiceTransport.RoundTrip in kernel/server/proxy/publish.go. The Publish Service runs on a separate, unauthenticated-by-default listener default TCP port 6808 and...

EUVD-2026-60097

opensslencrypt versions before 1.4.0 use an in-memory rate limiter for TOTP brute-force protection that is not shared across workers and is lost on server restart. Attackers can distribute authentication attempts across multiple server instances or retry immediately after a restart to bypass rate...

CVE-2026-74878

openssl_encrypt versions before 1.4.0 contain a TOTP brute-force rate limiter bypass in openssl_encrypt_server/modules/pepper/totp.py. The TOTPRateLimiter class stores attempt and lockout state in an in-memory defaultdict(list) as a class variable, meaning rate-limit state is not shared across wo...
