CVE-2020-2286
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 Role-based Authorization Strategy Plugin 3.0 and earlier does not properly invalidate a permission cache when the configuration is changed, resulting in permissions being granted based on an outdated configuration.
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 Role-based Authorization Strategy Plugin versions 3.0 and earlier fails to properly invalidate the permission cache when authorization configuration is changed. This causes the plugin to grant or deny access based on stale, outdated authorization settings rather than the current configuration.

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.
-
Check if Role-based Authorization Strategy plugin is installedNavigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab. Search for 'Role-based Authorization Strategy' in the list of installed plugins.Affected if The plugin is not found in the installed list, then this CVE does not apply.
-
Identify the installed plugin versionIn the same plugin list, locate the 'Role-based Authorization Strategy' entry and note the version number displayed in the Version column.Affected if Version is 3.0 or earlier, indicating the plugin is vulnerable to stale permission caching.
-
Verify the authorization strategy in useNavigate to Manage Jenkins > Configure Global Security > Authorization section. Check which authorization strategy is selected.Affected if The 'Role-Based Strategy' option is selected, meaning the vulnerable plugin is actively enforcing authorization.
-
Confirm cache behavior after configuration changesMake a minor change to the role assignments (such as adding or removing a user from a role), then immediately attempt to access resources that should be affected by the change. Observe whether access rights reflect the old configuration instead of the new one.Affected if Access permissions still reflect the previous configuration after making changes, indicating the cache invalidation flaw is present.
User is affected if the Role-based Authorization Strategy plugin version is 3.0 or earlier and the plugin is actively used as the authorization strategy in Jenkins.
