…sitive (#1441) ## Rationale OWASP dependency-check flagged CVE-2026-54399 (HTTP/1.1 parser DoS) and CVE-2026-54428 (HTTP/2 HPACK decoder DoS), both scoped to Apache HttpComponents Core "up to and including 5.4.2". Two things were needed: the classic httpcore 4.x artifact is not affected (4.x has no HTTP/2 module and no fixed 4.4.x release exists for these 5.x-scoped CVEs), so it is suppressed as a false positive; and the real exposure is httpcore5-h2, which was resolving transitively to 5.3.6 because the resolutionStrategy force block pinned httpcore5 and httpclient5 but not httpcore5-h2. ## Related Pull Requests - #1440 ## Changes - Force `org.apache.httpcomponents.core5:httpcore5-h2` to `httpcore5Version` (5.4.3), upgrading the transitive 5.3.6 past the vulnerable 5.4.2 ceiling and clearing both CVEs. Verified via `:server:modules:platform:api:dependencies` (`5.3.6 -> 5.4.3`). - Suppress false positive CVE-2026-54428 on the classic httpcore 4.x artifact. ## Note on shaded copies Shaded copies of these http5 libraries originate from labkey-api-jdbc (`:remoteapi:labkey-api-jdbc`, only wired into the build under the `all` settings/module set) and are being addressed separately. They do not appear in a `-PmoduleSet=community` scan because that project is out of scope there. <!-- list of standard tasks (remove this comment to enable) ## Tasks 📍 - [ ] Claude Code Review - [ ] Manual Testing - [ ] Test Automation - [ ] Verify Fix -->

Rationale
LabKey Server's OWASP Dependency Check build is failing on develop with 124 findings, the bulk of them from a handful of vulnerable third-party dependencies. This PR clears the findings that can be resolved by version bumps/forces and suppresses two verified false positives.
