CVE-2026-10078: Use of HTTP Request With Sensitive Query String in Red Hat Red Hat Quay 3
A flaw was found in the Quay config-tool's GitLab OAuth validator. This vulnerability causes sensitive credentials, specifically client_id and client_secret, to be transmitted as plaintext in URL query parameters during POST requests to the GitLab endpoint. This insecure transmission can lead to the disclosure of these credentials in various system logs, such as server access logs, reverse proxy logs, and other monitoring systems. An attacker with access to these logs could potentially obtain these credentials, leading to unauthorized information disclosure.
AI Analysis
Technical Summary
The vulnerability involves the transmission of sensitive OAuth credentials (client_id and client_secret) in the URL query string during POST requests to the GitLab endpoint by the Quay config-tool's GitLab OAuth validator in Red Hat Quay 3. Because URLs and their query parameters are commonly logged by servers and proxies, this practice risks exposing these credentials in plaintext within logs. The CVSS 3.1 base score is 2.7, indicating a low severity issue with network attack vector, low complexity, and requiring high privileges. No official fix or patch is currently documented in the vendor advisory.
Potential Impact
The primary impact is the potential unauthorized disclosure of sensitive OAuth credentials if an attacker gains access to system or proxy logs containing the plaintext query strings. This could lead to credential compromise and unauthorized access to GitLab OAuth-protected resources. However, exploitation requires access to logs and high privileges, limiting the overall risk. There is no indication of direct impact on system integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-10078 for current remediation guidance. Until an official fix is available, organizations should minimize log exposure of URLs containing sensitive query parameters, restrict access to logs, and consider alternative OAuth validation configurations that do not transmit credentials in query strings.
