6 new advisories for Composer packages

Two high-severity advisories stand out this week. Unbounded response header buffering in react/http can exhaust memory and cause denial of service. In leantime/leantime, any authenticated user can escalate to admin through unauthorised JSON-RPC methods. Update react/http to 1.11.1 and leantime/leantime to 3.10.0. Update yourls/yourls to 1.10.5 for unauthenticated file inclusion. Three drupal/core advisories cover Field UI remote code execution, Link module sanitisation and Navigation cross-site scripting. The Field UI issue is not directly exploitable with core alone. Fixed drupal/core versions are 10.6.19, 11.3.19, 11.4.10 and 12.0.0-beta2; use the version for your branch.
