## What is CVE-2026-30860?

CVE-2026-30860 is a critical SQL injection vulnerability in Tencent WeKnora, published on 7 Mar 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.2.12, a remote code execution (RCE) vulnerability exists in the application's database query functionality. The validation system fails to recursively inspect child nodes within PostgreSQL array expressions and row expressions, allowing attackers to bypass SQL injection protections. By smuggling dangerous PostgreSQL functions inside these expressions and chaining them with large object operations and library loading capabilities, an unauthenticated attacker can achieve arbitrary code execution on the database server with database user privileges. This issue has been patched in version 0.2.12.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)

Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-30860 exists.

Affected packages and fixed versions:
- github.com/Tencent/WeKnora (Go): affected all versions; no fix listed
- github.com/Tencent/WeKnora (Go): affected all versions; fixed in 0.2.12
- github.com/Tencent/WeKnora (Go): affected all versions; fixed in 0.2.12

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
