Jenkins plugins Multiple Vulnerabilities (2026-06-24)

high Nessus Plugin ID 322478

Synopsis

An application running on a remote web server host is affected by multiple vulnerabilities

Description

According to their self-reported version numbers, the version of Jenkins plugins running on the remote web server are affected by multiple vulnerabilities:

 - Jenkins OWASP ZAP Plugin 1.0.7 and earlier performs build operations on the Jenkins controller rather than the assigned agent, allowing attackers with Item/Configure permission to execute arbitrary code on the Jenkins controller. (CVE-2026-57301)

 - Jenkins Script Security Plugin 1402.v94c9ce464861 and earlier does not intercept the implicit type casts applied to the elements of typed for-each loops in sandboxed Groovy scripts, allowing attackers able to provide such scripts to invoke arbitrary constructors and bypass the sandbox protection. (CVE-2026-57280)

 - Jenkins Script Security Plugin 1402.v94c9ce464861 and earlier does not reject Groovy AST transformation annotations carrying an extensions member, allowing attackers able to run sandboxed Groovy scripts to execute code outside the sandbox if a suitable script is present on the classpath of the component that evaluates the script. (CVE-2026-57281)

 - Jenkins Git client Plugin 6.6.0 and earlier does not correctly escape the workspace directory name when it is embedded into a generated SSH wrapper script, allowing attackers able to control the name of a build's working directory to execute arbitrary operating system commands on the agent. (CVE-2026-57282)

 - A cross-site request forgery (CSRF) vulnerability in Jenkins Pipeline: Groovy Plugin 4331.v9d06ed4658ff and earlier allows attackers to instantiate types related to job or system configuration other than Pipeline steps through the Pipeline Snippet Generator. (CVE-2026-57283)

 - Jenkins Pipeline: Groovy Plugin 4331.v9d06ed4658ff and earlier does not restrict the types that can be instantiated through the Pipeline Snippet Generator, allowing attackers to instantiate types related to job or system configuration other than Pipeline steps. (CVE-2026-57284)

 - A missing permission check in Jenkins GitHub Branch Source Plugin 1967.1969.v205fd594c821 and earlier allows attackers with Overall/Read permission to obtain the URLs of GitHub Enterprise servers configured in the global plugin configuration. (CVE-2026-57285)

 - A missing permission check in Jenkins Git Parameter Plugin 462.vdcf3df2ed2ca_ and earlier allows attackers with Item/Read permission to obtain information about the SCM repository used by a job, such as branch names, tag names, and revision metadata. (CVE-2026-57286)

 - Jenkins Job Configuration History Plugin 1356.ve360da_6c523a_ and earlier does not redact the encrypted values of secrets when displaying historical job and agent configurations, allowing attackers with Extended Read permission to view encrypted secret values that would otherwise be redacted.
 (CVE-2026-57287)

 - Jenkins Active Directory Plugin 2.41.1 and earlier does not escape the user name before building the LDAP search filter in the Windows native (ADSI) authentication path, allowing unauthenticated attackers to inject LDAP wildcard characters to enumerate directory entries and to authenticate as a matching user whose password they know without knowing their exact user name. (CVE-2026-57288)

 - A missing permission check in Jenkins MCP Server Plugin 0.177.v629fdb_2557fe and earlier allows attackers with Item/Read permission to read the Pipeline replay scripts of jobs they can access. (CVE-2026-57300)

 - Jenkins Bitbucket Push and Pull Request Plugin 3.3.8 and earlier unconditionally disables SSL/TLS certificate and hostname validation for connections sending Bearer token authenticated requests to the configured Bitbucket Server endpoint, allowing attackers able to intercept network traffic to capture the token. (CVE-2026-57289)

 - A cross-site request forgery (CSRF) vulnerability in Jenkins Priority Sorter Plugin 936.v2c01c6b_84449 and earlier allows attackers to overwrite the global job priority configuration. (CVE-2026-57290)

 - Missing permission checks in Jenkins Gitee Plugin 1288.v18b_deb_c9069b_ and earlier allow attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method. (CVE-2026-57291)

 - A cross-site request forgery (CSRF) vulnerability in Jenkins Gitee Plugin 1288.v18b_deb_c9069b_ and earlier allows attackers to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method. (CVE-2026-57292)

 - An incorrect permission check in Jenkins Gitee Plugin 1288.v18b_deb_c9069b_ and earlier allows attackers with global Item/Configure permission (while lacking Item/Configure permission on any particular job) to enumerate credentials IDs of credentials stored in Jenkins. (CVE-2026-57293)

 - A missing permission check in Jenkins EC2 Fleet Plugin 4.2.3.539.v8fedff2a_81c3 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing AWS credentials stored in Jenkins.
 (CVE-2026-57294)

 - A cross-site request forgery (CSRF) vulnerability in Jenkins EC2 Fleet Plugin 4.2.3.539.v8fedff2a_81c3 and earlier allows attackers to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing AWS credentials stored in Jenkins. (CVE-2026-57295)

 - Jenkins External Workspace Manager Plugin 1.3.2 and earlier does not reject path traversal sequences in the custom workspace path provided to the exwsAllocate Pipeline step, allowing attackers with Item/Configure permission to read arbitrary files on the Jenkins controller file system, which can lead to remote code execution. (CVE-2026-57296)

 - A missing permission check in Jenkins Contrast Continuous Application Security Plugin 3.11 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL using an attacker- specified username, API key, and service key. (CVE-2026-57297)

 - A cross-site request forgery (CSRF) vulnerability in Jenkins Contrast Continuous Application Security Plugin 3.11 and earlier allows attackers to have Jenkins connect to an attacker-specified URL using an attacker-specified username, API key, and service key. (CVE-2026-57298)

 - Missing permission checks in Jenkins Contrast Continuous Application Security Plugin 3.11 and earlier allow attackers with Overall/Read permission to enumerate the names of configured Contrast metadata.
 (CVE-2026-57299)

 - Jenkins FitNesse Plugin 1.36 and earlier stores passwords unencrypted in job config.xml files on the Jenkins controller, where they can be viewed by users with Extended Read permission or access to the Jenkins controller file system. (CVE-2026-57302)

 - Jenkins Assembla Plugin 1.4 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks, allowing attackers able to control the responses of the configured Assembla server to extract secrets from the Jenkins controller or perform server-side request forgery. (CVE-2026-57303)

 - A missing permission check in Jenkins Assembla Plugin 1.4 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL using an attacker-specified username and password.
 (CVE-2026-57304)

 - A cross-site request forgery (CSRF) vulnerability in Jenkins Assembla Plugin 1.4 and earlier allows attackers to connect to an attacker-specified URL using an attacker-specified username and password.
 (CVE-2026-57305)

 - A cross-site request forgery (CSRF) vulnerability in Jenkins Zowe zDevOps Plugin 1.1.3.50.ve350c9b_450b_1 and earlier allows attackers to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins. (CVE-2026-57306)

 - A missing permission check in Jenkins Zowe zDevOps Plugin 1.1.3.50.ve350c9b_450b_1 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins. (CVE-2026-57307)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
