jenkins: no POST request is required for the endpoint handling manual build requests which could result in CSRF

A cross-site request forgery (CSRF) vulnerability in Jenkins 2.329 and earlier, LTS 2.319.1 and earlier allows attackers to trigger build of job without parameters when no security realm is set.

jenkins: DoS vulnerability in bundled XStream library

Jenkins 2.333 and earlier, LTS 2.319.2 and earlier defines custom XStream converters that have not been updated to apply the protections for the vulnerability CVE-2021-43859 and allow unconstrained resource usage.

jenkins: Agent-to-controller access control allows reading/writing most content of build directories

Jenkins 2.318 and earlier, LTS 2.303.2 and earlier allows any agent to read and write the contents of any build directory stored in Jenkins with very few restrictions.

jenkins: Agent-to-controller access control allowed writing to sensitive directory used by Pipeline: Shared Groovy Libraries Plugin

Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not limit agent read/write access to the libs/ directory inside build directories when using the FilePath APIs, allowing attackers in control of agent processes to replace the code of a trusted library with a modified variant. This results in unsandboxed code execution in the Jenkins controller process.

jenkins: FilePath#listFiles lists files outside directories with agent read access when following symbolic links.

FilePath#listFiles lists files outside directories that agents are allowed to access when following symbolic links in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.

jenkins: FilePath#toURI, FilePath#hasSymlink, FilePath#absolutize, FilePath#isDescendant, and FilePath#get*DiskSpace do not check any permissions

FilePath#toURI, FilePath#hasSymlink, FilePath#absolutize, FilePath#isDescendant, and FilePath#get*DiskSpace do not check any permissions in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.

jenkins: When creating temporary files, permission to create files is only checked after they’ve been created.

When creating temporary files, agent-to-controller access to create those files is only checked after they've been created in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.

jenkins: The operations FilePath#renameTo and FilePath#moveAllChildrenTo only check read permission on the source path

FilePath#renameTo and FilePath#moveAllChildrenTo in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier only check 'read' agent-to-controller access permission on the source path, instead of 'delete'.

jenkins: Creating symbolic links is possible without the symlink permission

Creating symbolic links is possible without the 'symlink' agent-to-controller access control permission in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.

jenkins: Agent processes are able to completely bypass file path filtering by wrapping the file operation in an agent file path

Agent processes are able to completely bypass file path filtering by wrapping the file operation in an agent file path in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.

jenkins: FilePath#unzip and FilePath#untar were not subject to any access control

FilePath#unzip and FilePath#untar were not subject to any agent-to-controller access control in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.

jenkins: FilePath#reading(FileVisitor) does not reject any operations allowing users to have unrestricted read access

The agent-to-controller security check FilePath#reading(FileVisitor) in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not reject any operations, allowing users to have unrestricted read access using certain operations (creating archives, FilePath#copyRecursiveTo).

jenkins: FilePath#untar does not check permission to create symbolic links when unarchiving a symbolic link

Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not check agent-to-controller access to create symbolic links when unarchiving a symbolic link in FilePath#untar.

jenkins: File path filters do not canonicalize paths, allowing operations to follow symbolic links to outside allowed directories

File path filters in the agent-to-controller security subsystem of Jenkins 2.318 and earlier, LTS 2.303.2 and earlier do not canonicalize paths, allowing operations to follow symbolic links to outside allowed directories.

jenkins: FilePath#mkdirs does not check permission to create parent directories

Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not check agent-to-controller access to create parent directories in FilePath#mkdirs.

The file browser in Jenkins 2.314 and earlier, LTS 2.303.1 and earlier may interpret some paths to files as absolute on Windows, resulting in a path traversal vulnerability allowing attackers with Overall/Read permission (Windows controller) or Job/Workspace permission (Windows agents) to obtain the contents of arbitrary files.

Jenkins 2.314 and earlier, LTS 2.303.1 and earlier accepts names of jobs and other entities with a trailing dot character, potentially replacing the configuration and data of other entities on Windows.

jenkins: session fixation vulnerability

Jenkins 2.299 and earlier, LTS 2.289.1 and earlier does not invalidate the previous session on login.

jenkins: improper permission checks allow canceling queue items and aborting builds

Jenkins 2.299 and earlier, LTS 2.289.1 and earlier allows users to cancel queue items and abort builds of jobs for which they have Item/Cancel permission even when they do not have Item/Read permission.

jenkins: view name validation bypass

Jenkins 2.286 and earlier, LTS 2.277.1 and earlier does not properly check that a newly created view has an allowed name, allowing attackers with View/Create permission to create views with invalid or already-used names.
