Timing Attack

Overview @perfood/couch-auth is an Easy and secure authentication for CouchDB/Cloudant. Based on SuperLogin, updated and rewritten in Typescript. Affected versions of this package are vulnerable to Timing Attack via a timing side-channel in the authentication process. An attacker can obtain...

OpenClaw has non-constant-time token comparison in hooks authentication

Summary OpenClaw hooks previously compared the provided hook token using a regular string comparison. Because this comparison is not constant-time, an attacker with network access to the hooks endpoint could potentially use timing measurements across many requests to gradually infer the token. In...
