CVE-2025-29155Public exploitNetwork attack vector

Unauthenticated record deletion via API key bypass

Published Sep 25, 2025 · Updated Sep 26, 2025

Authentication bypass in Swagger Petstore 1.0.7 allows remote attackers to delete arbitrary pet records through the DELETE endpoint. The DELETE /pet/{petId} handler accepts a forged or invalid API key without enforcing the endpoint's documented authorization requirement. No valid credentials are required; automated requests can erase multiple records, causing data loss and service disruption.
