High severity GitHub Reviewed Published Oct 29, 2025 to the GitHub Advisory Database • Updated Nov 5, 2025

Package

maven org.jenkins-ci.plugins:saml (Maven)

Affected versions

< 4.583.585.v22ccc1139f55

Patched versions

4.583.585.v22ccc1139f55

Description

Jenkins SAML Plugin 4.583.vc68232f7018a_ and earlier does not implement a replay cache.

This allows attackers able to obtain information about the SAML authentication flow between a user’s web browser and Jenkins to replay those requests, authenticating to Jenkins as that user.

SAML Plugin 4.583.585.v22ccc1139f55 implements a replay cache that rejects replayed requests.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Authentication Bypass by Capture-replay

A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes). Learn more on MITRE.
