OctoPrint has Timing Side-Channel Vulnerability in API Key Authentication

ImpactOctoPrint versions up to and including 1.11.5 are affected by a theoretical timing attack vulnerability that allows API key extraction over the network.Due to using character based comparison that short-circuits on the first mismatched character during API key validation, rather than a...

CVE-2026-4930

SYMCRYPTO is the SiXG301's host side hardware engine accessed by PSA crypto library that accelerates symmetric cryptographic operations AES encryption/decryption and hashing. DPA Countermeasures on SYMCRYPTO can be weakened reduced entropy by forcing certain seed values if an attacker gains code...
