The gap it fixes

CWE-918 (SSRF). Treating a URL as a plain string and checking whether an allowed host is a substring/prefix of it is a well-documented, structurally unsound validation pattern -- confirmed real and current via CVE-2024-22243 (Spring Framework, 2024): a regex mismatch in UriComponentsBuilder parsed the userinfo segment differently from the JDK's own URL handling, so https://evil.com[@127.0.0.1 passed a startsWith/getHost()-style check while the request's real host differed. This isn't a theoretical weakness -- it's a dated, named CVE in the exact framework this plugin's sinks target
