## Technical details

A hardcoded WhitePages reverse-phone API key was discovered in the 'wp1.php' file of Open ISES Tickets versions prior to 3.44.2. Because this key was committed to a public version control repository, it is accessible to any actor with read access to the source tree. An attacker can extract this credential and perform API calls that are billed to or rate-limited against the legitimate owner's account. This vulnerability is classified as CWE-798 (Use of Hard-coded Credentials). The issue was remediated in version 3.44.2 by removing the secret from the codebase.
