Authenticated RCE via Symlink Following in Cribl Stream Pack Git Import

Improper validation of symbolic links in the Pack Git import feature in Cribl Stream before 4.18.2 allows a remote authenticated attacker with Pack import and pipeline preview permissions to execute arbitrary code as the Cribl server process via a crafted Git repository containing a symbolic link in the pack's functions directory.

Code Injection in JSON Pointer Processing Component in Cribl Stream

Improper control of generation of code in the JSON Pointer-to-accessor compiler in Cribl Stream before 4.18.2 allows a remote authenticated attacker with edit privileges to execute arbitrary JavaScript on the server via a crafted database connection identifier or pack configuration value.

DOM-based XSS in Cribl Stream

DOM-based cross-site scripting (XSS) in Cribl Stream before 4.17.1 allows a remote attacker to execute arbitrary JavaScript in the browser of an authenticated user who is tricked into visiting a crafted URL and interacting with the page.

Local privilege escalation to SYSTEM in Cribl Edge for Windows

A vulnerability chain in Cribl Edge for Windows before 4.17.1 allows a local authenticated user to escalate privileges to NT AUTHORITY\SYSTEM. Incorrect default permissions on the Windows installer's authentication directory (CWE-276) expose a cryptographic secret used for JWT signing and password-hash derivation, enabling forgery of administrative API tokens. The forged token can then be used to invoke a pipeline function that reaches an OS command sink (CWE-78) running in the SYSTEM context.

Local privilege escalation in Cribl Edge for Linux

A command injection vulnerability in Cribl Edge for Linux versions 3.2.0 through 4.17.0 allows a local unprivileged user to execute arbitrary commands in the context of the Cribl Edge service account.

Cribl UI 1.5.0 allows remote attackers to run arbitrary commands via an unauthenticated web request.
