CVE-2026-74247
SUMMARY

A flaw was found in Red Hat Quay. A user with FEATURE_BUILD_SUPPORT enabled and repository write access can exploit a Server-Side Request Forgery (SSRF) vulnerability within the build API. This allows the user to provide a malicious URL, causing the Quay builder to make requests to internal network addresses. Such an action could lead to the disclosure of sensitive internal information.

CVE-2026-74245
SUMMARY

A flaw was found in Red Hat Quay's exported logs feature. An unauthenticated attacker with a valid file ID could download exported action logs without proper authorization. While file IDs are complex, they can be intercepted from plaintext email or webhook callbacks. This vulnerability leads to information disclosure, potentially exposing sensitive data such as usernames, email addresses, IP addresses, and action-specific metadata.

CVE-2026-74244
SUMMARY

A flaw was found in Red Hat Quay's Stripe billing webhook handler. This vulnerability allows an unauthenticated attacker to forge billing events by sending crafted JSON requests to the `/webhooks/stripe` endpoint without validating the Stripe-Signature header. Successful exploitation can lead to the unauthorized resetting of a namespace's build quota to its maximum and trigger unsolicited billing emails to namespace administrators.

CVE-2026-74243
SUMMARY

A flaw was found in Red Hat Quay. When the SECURITY_SCANNER_V4_PSK (pre-shared key) is not set, a remote unauthenticated attacker can send POST requests to the security scanner notification endpoint. This allows the attacker to flood the notification queue and inject path traversal characters into Clair API URL paths. The primary consequence is worker resource exhaustion and blind path manipulation on the configured Clair host, potentially leading to a denial of service.
