NVD Description

Note: Versions mentioned in the description apply only to the upstream osbuild-composer-dnf-json package and not the osbuild-composer-dnf-json package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

Fulcio is a certificate authority for issuing code signing certificates for an OpenID Connect (OIDC) identity. Prior to 1.8.5, Fulcio's metaRegex() function uses unanchored regex, allowing attackers to bypass MetaIssuer URL validation and trigger SSRF to arbitrary internal services. Since the SSRF only can trigger GET requests, the request cannot mutate state. The response from the GET request is not returned to the caller so data exfiltration is not possible. A malicious actor could attempt to probe an internal network through Blind SSRF. This vulnerability is fixed in 1.8.5.
