Primary sources: NVD · CVE.org · FIRST EPSS

Jenkins SAML Single Sign On(SSO) Plugin 2.1.0 and earlier unconditionally disables SSL/TLS certificate validation for connections to miniOrange or the configured IdP to retrieve SAML metadata, which could be abused using a man-in-the-middle attack to intercept these connections.

Weakness class (CWE)

CWE-295 · Improper Certificate Validation

CVSS vector

CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N

Root cause

A certificate validation error is silently swallowed instead of terminating the connection. Often, code added for a test environment makes its way into production.
