/api/images/presigned-url을 관리자 전용으로 제한하세요.
ADMIN_ACCESSIBLE_URIS에 등록해도 일반 사용자 토큰에는 역할 검사가 적용되지 않습니다. 현재 ImageController도 인증 주체나 소유권을 확인하지 않고 presigned URL을 발급합니다.
anyRequest() 앞에 다음 규칙을 추가하세요.
.requestMatchers(HttpMethod.GET, "/api/images/presigned-url").hasRole("ADMIN")authenticated()는 인증 여부만 확인하므로 관리자 제한에는 hasRole이 필요합니다. (Spring Security 공식 문서)

🧾 요약
GET /api/images/presigned-url)에서 403이 나던 문제를 수정합니다.🔗 이슈
✨ 변경 내용
SecurityConfig.ADMIN_ACCESSIBLE_URIS에/api/images/presigned-url추가배경
JwtFilter는admin.id/user.id가 같은 숫자 공간을 쓰는 문제 때문에, ADMIN 토큰을ADMIN_ACCESSIBLE_URIS에 등록된 경로에서만 인증한다. presigned URL 엔드포인트가 목록에 없어 관리자 업로드가 403으로 막혔다.✅ 확인
