What is CVE-2026-10078?
CVE-2026-10078 is a low-severity vulnerability in Red Hat Quay 3, published on 29 May 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
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.
