Project: Examples for Developers [1] Date: 2020-November-18 Security risk: *Critical* 17∕25 AC:Basic/A:User/CI:All/II:All/E:Theoretical/TD:Default [2] Vulnerability: Remote Code Execution
Description: The File Example submodule within the Examples project does not properly sanitize certain filenames as described in SA-CORE-2020-012 [3], along with other related vulnerabilities.
Therefore, File Example so is being removed from Examples until a version demonstrating file security best practices can added back in the future.
Solution: Any sites that have File Example submodule installed should uninstall it immediately
Then, install the latest version of Examples:
* If you use Examples 3 (Drupal 9-compatible), upgrade to Examples 3.0.2 [4] * If you use the Examples module's 8.x-1.x branch, upgrade to Examples 8.x-1.1 [5]
