XXE vulnerability in Plot Plugin
Plot Plugin 2.1.11 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.
This allows attackers able to control XML input files for the 'Plot build data' build step to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.
Plot Plugin 2.1.12 disables external entity resolution for its XML parser.
Open redirect vulnerability in Google Login Plugin
Google Login Plugin 1.4 through 1.6 (both inclusive) improperly determines that a redirect URL after login is legitimately pointing to Jenkins.
This allows attackers to perform phishing attacks by having users go to a Jenkins URL that will forward them to a different site after successful authentication.
Google Login Plugin 1.7 only redirects to relative (Jenkins) URLs.
Stored XSS vulnerability in Checkmarx Plugin
Checkmarx Plugin processes Checkmarx service API responses and generates HTML reports from them for rendering on the Jenkins UI.
Checkmarx Plugin 2022.3.3 and earlier does not escape values returned from the Checkmarx service API before inserting them into HTML reports. This results in a stored cross-site scripting (XSS) vulnerability.
While Jenkins users without Overall/Administer permission are not allowed to configure the URL to the Checkmarx service, this could still be exploited via man-in-the-middle attacks.
Checkmarx Plugin 2022.4.3 escapes values returned from the Checkmarx service API before inserting them into HTML reports.
Improper credentials masking in Gitea Plugin
Gitea Plugin support authentication with Gitea personal access tokens.
In Gitea Plugin 1.4.4 and earlier, the implementation of these tokens did not support credentials masking. This can expose Gitea personal access tokens in the build log, e.g., when printed as part of repository URLs.
Gitea Plugin 1.4.5 adds support for masking of Gitea personal access tokens.
Administrators unable to update are advised to use SSH checkout instead.
Stored XSS vulnerability in Custom Build Properties Plugin
Custom Build Properties Plugin 2.79.vc095ccc85094 and earlier does not escape property values and build display names on the Custom Build Properties and Build Summary pages.
This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to set or change these values.
Custom Build Properties Plugin 2.82.v16d5b_d3590c7 escapes property values and build display names on the Custom Build Properties and Build Summary pages.
Stored XSS vulnerability in Spring Config Plugin
Spring Config Plugin 2.0.0 and earlier does not escape build display names shown on the Spring Config view.
This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to change build display names.
Spring Config Plugin 2.0.1 escapes build display names shown on the Spring Config view.
CSRF vulnerability in Sonar Gerrit Plugin
Sonar Gerrit Plugin 377.v8f3808963dc5 and earlier does not require POST requests for an HTTP endpoint, resulting in a cross-site request forgery (CSRF) vulnerability.
This allows attackers to have Jenkins connect to Gerrit servers (previously configured by Jenkins administrators) using attacker-specified credentials IDs obtained through another method, potentially capturing credentials stored in Jenkins.
