CVE-2026-23996

CVE-2026-23996 concerns the FastAPI Api Key library. Version 1.1.0 is reported to expose a timing side-channel in verify_key(), where a random delay is applied only on verification failures. This enables an attacker to statistically distinguish valid from invalid API keys by measuring response la...

A flaw was found in openCryptoki. The openCryptoki Soft token does not check if an EC key is valid when an EC key is created via C_CreateObject nor when C_DeriveKey is used with ECDH public data. This may allow a malicious user to extract the private key by performing an invalid curve attack.
