CVE-2025-70821
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedrenren-secuity before v5.5.0 is vulnerable to SQL Injection in the BaseServiceImpl.java component
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceSQL Injection vulnerability in renren-security's BaseServiceImpl.java allows attackers to inject malicious SQL queries through unsanitized input processed by the service layer before reaching the database. The critical severity (9.8) indicates direct exploitation potential with high impact on data confidentiality, integrity, and availability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed version of renren-securityLocate the project version in your build configuration (pom.xml, build.gradle, or WAR/Maven artifact metadata) and note the version numberAffected if The version is 5.5.0 or lower (any version <= 5.5.0 is affected)
-
Locate the BaseServiceImpl.java file in your codebaseSearch your source tree for the file named BaseServiceImpl.java - it is typically found in the service implementation package under the main application sourceAffected if The file exists in your codebase and the version from step 1 is <= 5.5.0
-
Inspect BaseServiceImpl.java for dynamic SQL constructionOpen BaseServiceImpl.java and search for dynamic query patterns such as string concatenation with user input, direct SQL string building, or Query/Example objects used with unsanitized parametersAffected if The file contains dynamic query construction where user-supplied input is concatenated directly into SQL strings without using parameterized queries
-
Verify if PreparedStatement or parameterized queries are usedReview the service methods in BaseServiceImpl.java that process input parameters and check whether they use PreparedStatement with placeholders (?) or JPA Specifications/Example with proper parameter bindingAffected if The code does NOT use parameterized queries - user input flows directly into dynamic SQL without binding parameters
You are affected if your renren-security version is 5.5.0 or lower AND BaseServiceImpl.java contains dynamic SQL construction that processes user input without parameterized queries.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade renren-security to v5.5.0 or later. Until patched, audit BaseServiceImpl.java for dynamic query construction and implement parameterized queries/PreparedStatement usage for all user-supplied input.
Upgrade to Renren Security v5.5.0 or later
- 1. Identify the current version of Renren Security deployed in your environment
- 2. If running a version before v5.5.0, plan for upgrade to v5.5.0 or later
- 3. Backup the existing application configuration and database before upgrading
- 4. Upgrade Renren Security to version 5.5.0 or the latest stable release
- 5. Verify the BaseServiceImpl.java component has been updated in the new version
- 6. Test the application functionality to ensure the upgrade does not introduce regressions
- 7. Monitor application logs for any SQL injection attempts or errors
