Improper Validation of Array Index

Overview Affected versions of this package are vulnerable to Improper Validation of Array Index via the DecryptBytes function. An attacker can cause the process or goroutine to crash by sending a crafted AES-CBC encrypted assertion with a plaintext of all zero bytes, which triggers a panic due to...

GHSA-HWQM-QVJ9-4JR2 gosaml2 CBC Padding Panic — Unauthenticated Process Crash

Summary The AES-CBC decryption path in DecryptBytes panics on crafted ciphertext whose plaintext is all zero bytes. After decryption, bytes.TrimRightdata, "\x00" empties the slice, then datalendata-1 panics with index out of range -1. There is no recover in the library. The panic propagates throu...

SiYuan has an Unauthenticated WebSocket DoS via Auth Keepalive Bypass

Summary The SiYuan kernel WebSocket server accepts unauthenticated connections when a specific “auth keepalive” query parameter is present. After connection, incoming messages are parsed using unchecked type assertions on attacker-controlled JSON. A remote attacker can send malformed messages tha...
