Jenkins Coverage Plugin 2.3054.ve1ff7b_a_a_123b_ and earlier does not validate the configured coverage results ID when creating coverage results, only when submitting the job configuration through the UI, allowing attackers with Item/Configure permission to use a `javascript:` scheme URL as identifier by configuring the job through the REST API, resulting in a stored cross-site scripting (XSS) vulnerability.

Jenkins Coverage/Complexity Scatter Plot Plugin 1.1.1 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

Jenkins Coverage/Complexity Scatter Plot Plugin 1.1.1 and earlier does not escape the method information in tooltips, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to provide report files to the plugin's post-build step.
