SCA: security update for github.com/oauth2-proxy/oauth2-proxy/v7 (GHSA-7rh7-c77v-6434)

critical Tenable Cloud Security Plugin ID 428691

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OAuth2-Proxy is an open-source tool that can act as either a standalone reverse proxy or a middleware
 component integrated into existing reverse proxy or load balancer setups. In versions 7.10.0 and below,
 oauth2-proxy deployments are vulnerable when using the skip_auth_routes configuration option with regex
 patterns. Attackers can bypass authentication by crafting URLs with query parameters that satisfy
 configured regex patterns, allowing unauthorized access to protected resources. The issue stems from
 skip_auth_routes matching against the full request URI. Deployments using skip_auth_routes with regex
 patterns containing wildcards or broad matching patterns are most at risk. This issue is fixed in version
 7.11.0. Workarounds include: auditing all skip_auth_routes configurations for overly permissive patterns,
 replacing wildcard patterns with exact path matches where possible, ensuring regex patterns are properly
 anchored (starting with ^ and ending with $), or implementing custom validation that strips query
 parameters before regex matching. (CVE-2025-54576)
