PT-2026-73343

Jenkins 2.575 and earlier, LTS 2.568.1 and earlier does not safely handle symbolic links with effectively empty names during the extraction of .tar and .tar.gz archives, allowing attackers able to control agent processes to provide crafted archives to the controller to write files to arbitrary...

PT-2026-73346

Jenkins 2.575 and earlier, LTS 2.568.1 and earlier does not restrict the types of objects that can be instantiated as part of the project naming strategy configuration, allowing attackers with Overall/Manage permission to instantiate arbitrary types related to configuration, including those...

Jenkins - Remote Command Injection

Jenkins 2.153 and earlier and LTS 2.138.3 and earlier are susceptible to a remote command injection via stapler/core/src/main/java/org/kohsuke/stapler/MetaClass.java that allows attackers to invoke some methods on Java objects by accessing crafted URLs that were not intended to be invoked this wa...

Jenkins GitHub Plugin <=1.29.1 - Server-Side Request Forgery

Jenkins GitHub Plugin 1.29.1 and earlier is susceptible to server-side request forgery via GitHubTokenCredentialsCreator.java, which allows attackers to leverage attacker-specified credentials IDs obtained through another method and capture the credentials stored in Jenkins. id: CVE-2018-1000600...

ROS-20260813-73-0001

The vulnerability in Jenkins is related to the redirection of URLs to an unreliable website. Exploiting this vulnerability allows a malicious actor to redirect users to arbitrary URL addresses...

CVE-2026-70427

A flaw was found in Jenkins. Attackers who can control agent processes can exploit this vulnerability by providing specially crafted .tar or .tar.gz archives to the Jenkins controller. This is due to unsafe handling of symbolic links with effectively empty names during archive extraction...

CVE-2026-70430

A flaw was found in Jenkins. This vulnerability allows an attacker with Overall/Manage permission to instantiate arbitrary types of objects within the project naming strategy configuration. This includes types typically reserved for administrators, potentially leading to unauthorized configuratio...

CVE-2026-70429

A flaw was found in Jenkins. Due to inconsistent handling of case sensitivity in user and group names, an attacker with the ability to create new users or groups could exploit this vulnerability. By crafting user or group names that case-insensitively match existing ones, the attacker could...

CVE-2026-19429

A flaw was found in Jenkins. An authenticated remote attacker with low privileges could exploit an incomplete patch related to symlink validation during tar archive extraction. This vulnerability allows the attacker to bypass symlink target validation, enabling them to read arbitrary files on the...

CVE-2026-70426

A flaw was found in Jenkins Remoting. This vulnerability allows agent processes, code running on agents, and attackers with Agent/Connect permission to bypass the JEP-200 deserialization filter. This bypass occurs because the filter is not applied to classes resolved through a fallback path in th...

CVE-2026-19429 Jenkins - FilePath.untarFrom() Symlink Target Validation Bypass and Blank-Name Check Bypass (Arbitrary File Read)

Jenkins FilePath.untarFrom does not validate symlink targets in extracted TAR archives, even in versions patched for CVE-2026-33001 and CVE-2026-70427. An authenticated attacker with job configuration privileges can include a malicious archive in a build step that creates workspace symlinks...

CVE-2026-19429

CVE-2026-19429 relates to Jenkins FilePath.untarFrom() where TAR extraction does not validate tar entry symlink targets, allowing an authenticated user with Item/Configure privileges to create workspace symlinks that point to arbitrary files on the Jenkins controller. This can enable reading sens...

EUVD-2026-55615

Jenkins FilePath.untarFrom in all versions, including those with the CVE-2026-33001 patch applied, validates symlink destinations but not targets. The CVE-2026-33001 fix enforces that the symlink file is created within the workspace boundary, but the symlink target — the path returned by...

CVE-2026-19429

Jenkins FilePath.untarFrom does not validate symlink targets when extracting TAR archives, allowing an attacker with Item/Configure permission to create symlinks from a workspace to arbitrary files on the Jenkins controller. This issue remains exploitable in versions patched for CVE-2026-33001 an...
