Chainguard: multiple localstack packages: security update to 4.14.0-r29

high Tenable Self-Hosted Container Security Plugin ID 473497

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - PyMongo's connection string parsing decodes percent-encoded characters in the host portion before the host
 list is separated on its delimiters. When an application places a hostname value supplied by an
 unauthenticated party into a connection string, that party may cause additional servers of their choosing
 to be added to the application's database client. The application may then send its authentication
 exchange and database operations to one of those servers, which can observe limited information and return
 altered results. (CVE-2026-96748)

Solution

Update the localstack library and its related packages to version 4.14.0-r29 or later.
