Jenkins FilePath.untarFrom() (all versions) validates symlink destinations but not targets, bypassing CVE-2026-33001. Any user with Item/Build access triggers tar extraction via POST /job/{name}/build, writing persistent symlinks into the tool cache. Symlinks to secrets/master.key, hudson.util.Secret, credentials.xml, and users/*/config.xml read via GET /job/{name}/lastBuild/consoleText enable offline AES decryption of all credentials and admin API tokens without bcrypt cracking, achieving RCE. |
