Jenkins ≫ Jenkins

Jenkins 2.335 through 2.355 (both inclusive) allows attackers in some cases to bypass a protection mechanism, thereby directly accessing some view fragments containing sensitive information, bypassing any permission checks in the corresponding view.

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.

XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resul...

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.

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 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.

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, Fi...

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.

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.

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.
