SCA: security update for rollup (GHSA-mw96-cpmx-2vgc)
critical Tenable Cloud Security Plugin ID 438026
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Rollup is a module bundler for JavaScript. Versions prior to 2.80.0, 3.30.0, and 4.59.0 of the Rollup
module bundler (specifically v4.x and present in current source) is vulnerable to an Arbitrary File Write
via Path Traversal. Insecure file name sanitization in the core engine allows an attacker to control
output filenames (e.g., via CLI named inputs, manual chunk aliases, or malicious plugins) and use
traversal sequences (`../`) to overwrite files anywhere on the host filesystem that the build process has
permissions for. This can lead to persistent Remote Code Execution (RCE) by overwriting critical system or
user configuration files. Versions 2.80.0, 3.30.0, and 4.59.0 contain a patch for the issue.
