CVE-2023-33005
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedJenkins WSO2 Oauth Plugin 1.0 and earlier does not invalidate the previous session on login.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Jenkins WSO2 OAuth Plugin versions 1.0 and earlier contains a session fixation vulnerability where it fails to invalidate the previous session upon user login. This could allow an attacker who has obtained a valid session ID to maintain access after the legitimate user authenticates via OAuth.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if WSO2 OAuth Plugin is installedNavigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab, or run: jenkins-cli.jar get-plugins (or via /pluginManager/installed API). Look for 'wso2-oauth' or 'WSO2 OAuth' in the plugin list.Affected if The plugin named WSO2 OAuth or wso2-oauth appears in the installed plugins list.
-
Determine the installed plugin versionIn the installed plugins list, note the version number shown next to the WSO2 OAuth plugin. If using CLI/API, retrieve the plugin's manifest or version metadata.Affected if The version is 1.0 or any version lower than 1.0 (e.g., 0.x, 1.0-beta, etc.).
-
Verify OAuth authentication is configuredCheck Jenkins > Manage Jenkins > Configure Global Security > Security Realm. Look for WSO2 OAuth, OAuth2, or similar WSO2-based authentication option selected as the security realm.Affected if WSO2 OAuth or WSO2 OAuth-based authentication is selected as the active Security Realm, meaning users authenticate via the vulnerable OAuth flow.
-
Inspect session handling configurationIf accessible, review Jenkins > Manage Jenkins > Configure Global Security for any session-related settings, or check the plugin's configuration page under Manage Jenkins. Look for session timeout, session fixation protection, or session management options specific to the OAuth plugin.Affected if Session fixation protection is not explicitly enabled or configured; the plugin relies on default session handling.
You are affected if the WSO2 OAuth plugin version 1.0 or earlier is installed AND WSO2 OAuth authentication is actively configured as the security realm in Jenkins.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to a patched version of the WSO2 OAuth Plugin when released. Until then, monitor session activity closely and consider implementing additional session monitoring controls.
