Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

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.

This lack of validation could be abused using a man-in-the-middle attack to intercept these connections.

SAML Single Sign On(SSO) Plugin 2.2.0 performs SSL/TLS certificate validation when connecting to miniOrange or the configured IdP to retrieve SAML metadata.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jenkins.plugins:miniorange-saml-sp, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update io.jenkins.plugins:miniorange-saml-sp to 2.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-32994 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
