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...

CVE-2026-23996 FastAPI Api Key has a timing side-channel in verify_key that allows statistical key validity detection

FastAPI Api Key provides a backend-agnostic library that provides an API key system. Version 1.1.0 has a timing side-channel vulnerability in verifykey. The method applied a random delay only on verification failures, allowing an attacker to statistically distinguish valid from invalid API keys b...
