CVE-2026-74245
Description
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.
Statement
This Moderate impact flaw in Red Hat Quay's exported logs feature allows unauthenticated download of sensitive log data. While file IDs are complex, their transmission via plaintext email and webhooks creates interception opportunities. Deployments using LocalStorage backends are at higher risk due to indefinite log file persistence.
Mitigation
To mitigate the risk, configure Red Hat Quay to use a cloud storage backend for exported logs, which provides time-limited download URLs. Additionally, ensure that all communication channels used for delivering exported log file IDs, such as email and webhook callbacks, are adequately secured to prevent plaintext interception.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Access Control,Other
Technical Impact: Gain Privileges or Assume Identity; Varies by Context
Exposing critical functionality essentially provides an attacker with the privilege level of that functionality. The consequences will depend on the associated functionality, but they can range from reading or modifying sensitive data, accessing administrative or other privileged functionality, or possibly even executing arbitrary code.
