CVE-2026-40964


Authentication Bypass in cf-auth-proxy in Cloud Foundry Foundation all installations allows an unauthenticated remote attacker to gain read access to every log and metric for every application and platform component via minting a JWT that the cf-auth-proxy accepts as a valid logs.admin token. Affected versions: - log-cache_release: all versions through v3.2.6 (inclusive); fixed in v3.2.7 or later - CF Deployment: all versions through v55.?.0 (inclusive); fixed in v55.?.0 or later (bundles log-cache_release v3.2.7)


Security Impact Summary

This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 7.5, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), for affected systems.

Historical Context

Reported in 2026, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For affected software, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
