### #安全整改
这个 PR 主要是一次安全整改,重点包括:

  • 修复动态 SQL 注入和 OGNL 注入问题,校验表名、字段名、排序条件,并使用参数绑定。
  • 增强动态表结构修改、文件路径和数据库清理的安全校验。
  • 修复 AI 请求中的 SSRF 风险,限制请求地址。
  • 将 SM4 从 ECB 模式升级为 GCM 模式。
  • 改进异常处理,保留原始异常原因。
  • 增加 CodeQL、PMD、Checkstyle 配置和相关测试。
  • 修复 AI 消息为空、动态字段类型不一致等问题。
    整体目标是降低安全扫描告警,同时补充测试和代码规范

Walkthrough

The pull request adds dynamic CodeQL workflows, strengthens dynamic SQL validation and binding, confines RAG file operations to a configured root, replaces SM4/ECB with SM4/GCM, and updates application input and null handling.

Changes

CodeQL workflows

Layer / File(s) Summary
Dynamic language matrix
.github/scripts/codeql-matrix.sh
The script detects tracked language files and emits the CodeQL matrix.
Incremental CodeQL workflow
.github/workflows/codeql.yml
The workflow detects languages at runtime and runs matrix-based incremental analysis.
Full CodeQL workflow and reporting
.github/workflows/codeql-full.yml
The workflow performs full scans, creates SARIF and HTML reports, uploads artifacts, and validates findings.

Dynamic SQL validation

Layer / File(s) Summary
Central validation and escaping
base/src/main/java/com/tinyengine/it/common/utils/SqlIdentifierValidator.java, base/src/test/java/com/tinyengine/it/common/utils/SqlIdentifierValidatorTest.java
Identifier and order validation now use explicit checks. SQL literal escaping is centralized and tested.
Bound dynamic SQL operations
base/src/main/java/com/tinyengine/it/dynamic/dao/DynamicSqlProvider.java
Dynamic SQL validates names, binds values, validates pagination, normalizes count fields, and rejects incomplete inputs.
Validated table and column generation
base/src/main/java/com/tinyengine/it/dynamic/service/DynamicModelService.java, base/src/main/java/com/tinyengine/it/dynamic/service/DynamicService.java
Table, column, order, default, comment, and enum values receive centralized validation or escaping.

RAG document path handling

Layer / File(s) Summary
Document-root injection
base/src/main/java/com/tinyengine/it/rag/config/RAGConfig.java, base/src/main/java/com/tinyengine/it/rag/config/VectorStoreConfig.java
The document root is configured through RAGConfig and injected into StorageService.
Safe document path resolution
base/src/main/java/com/tinyengine/it/rag/service/StorageService.java
Path resolution normalizes inputs, blocks escapes from the root, checks symlinks, and returns absolute scan paths.
Resolved load and delete operations
base/src/main/java/com/tinyengine/it/rag/service/StorageService.java
Load, initialize, and delete operations validate and use resolved document paths.

Application security and robustness

Layer / File(s) Summary
Authenticated SM4 encryption
base/src/main/java/com/tinyengine/it/common/utils/SM4Utils.java, base/src/test/java/com/tinyengine/it/common/utils/SM4UtilsTest.java
SM4 uses GCM mode, random nonces, combined payloads, key-length checks, and round-trip tests.
Chat token and URL handling
base/src/main/java/com/tinyengine/it/service/app/impl/AiChatServiceImpl.java, base/src/main/java/com/tinyengine/it/service/app/impl/v1/AiChatV1ServiceImpl.java
Token checks use character validation. URL validation returns the validated URI and rejects user info and fragments.
Explicit validation and null-safe handling
base/src/main/java/com/tinyengine/it/service/material/impl/BlockServiceImpl.java, base/src/main/java/com/tinyengine/it/service/material/impl/ModelServiceImpl.java, app/src/main/java/com/tinyengine/it/task/DatabaseCleanupService.java
Positive-integer checks and Boolean handling are explicit. Cleanup logging and exception handling are centralized.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 81b04

The change can break existing encrypted credentials, retain deleted symlinked documents in the knowledge base, narrow dynamic-model columns, and generate invalid pagination offsets. These should be corrected before merge.

A rabbit checks the matrix bright,
Then guards each path by root at night.
GCM keys hum, SQL names align,
Safe tokens hop in a neat line.

existing pagination behavior.

null; avoid concatenating content so the literal "null" is never included, while
preserving the existing handling for non-null content.

path stored by loadDocuments and used by searchBySource; inherited
deleteMultipleFiles and clearCollection behavior should remain unchanged.

PR #328 代码复核记录

经本地构建与运行验证,主要发现汇总如下(具体代码位置与修改建议见下方各代码行批注):

  1. 测试执行状态DynamicModelService 字段更名未同步修改单测中的反射注入,导致 DynamicModelServiceTest 16 个单元测试报错(因 CI 跳过测试,未在流水线中体现)。
  2. 逻辑与行为差异
    • 表结构修改(modifyTableStructure):白名单未包含 DATETIME 且存在大小写差异,执行时会抛出异常。
    • URL 校验:validateFinalUrl 拦截以 # 结尾的 URL,与上游处理逻辑冲突。
    • 异常捕获:多处收窄为 IllegalArgumentException,底层异常无法进入降级分支。
    • SQL 拼接:BlockServiceImpl 标签条件仍为字符串拼接,未做参数化绑定。
  3. 配置与规范
    • 调整了 pom.xml 门禁参数并新增较多 PMD 抑制注解。
    • ChromaConnectionProbe Javadoc 位于注解后未生效;codeql-full.yml 缺少路径排除配置文件。
    • 包含较多排版与空白字符变更,建议与功能代码分离提交。

建议处理清单:

  • 1. 修正 DynamicModelServiceTest 反射字段名,确保本地单测通过。
  • 2. 统一表结构修改类型白名单,恢复 VectorStoreConfig 异常捕获范围,对齐 URL # 校验逻辑。
  • 3. 将标签拼接调整为参数化绑定,评估 pom.xml 门禁配置与抑制注解。
  • 4. 为 codeql-full.yml 补充配置文件路径,规范提交信息并分离格式化改动。

此处对传入的标签名列表进行字符串拼接并传入 queryWrapper.apply(...),未做参数化绑定。
建议采用安全参数绑定或对 label 值增加校验。

当前解密逻辑中,未带 GCM_PREFIX 前缀的数据在 GCM 解密失败后会自动进入 decryptLegacyEcb。
若密文被剥离前缀,可能触发降级到 ECB 解密路径。建议评估是否需要对历史存量数据进行迁移并逐步限制 ECB 回退。

本次修改中调整了 minimumPriority 与 failurePriority,并设置 maxAllowedViolations 为 51、failOnViolation 为 false;同时代码中新增了 182 处 PMD 抑制注解。
建议评估门禁规则设置,恢复既有质量门禁基线,并针对确需保留的抑制项逐处说明原因。

类 Javadoc 注释当前位于 @SuppressWarnings 注解之后、@component 之前。Checkstyle 及 JavaDoc 解析器不会将其识别为类文档注释。
