## What is CVE-2026-40967?

CVE-2026-40967 is a high-severity code injection vulnerability in Spring AI, published on 28 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

In Spring AI, various FilterExpressionConverter implementations accept a filter expression object and translate them to specific vector store query languages. In several cases, keys and values are not properly escaped, leading to the ability to alter the query.

Affected versions:
Spring AI: 1.0.0 - 1.0.5 (fixed in 1.0.6), 1.1.0 - 1.1.4 (fixed in 1.1.5)

Weakness: CWE-94 (Improper Control of Generation of Code)

Check this codebase for CVE-2026-40967 and fix it if it is affected.

What it is: CVE-2026-40967 is a high-severity code injection vulnerability in Spring AI, published on 28 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-40967 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.springframework.ai:spring-ai-vector-store (Maven): affected from 1.0.0; fixed in 1.0.6
- org.springframework.ai:spring-ai-vector-store (Maven): affected from 1.0.0; fixed in 1.0.6
- org.springframework.ai:spring-ai-vector-store (Maven): affected from 1.1.0; fixed in 1.1.5
- org.springframework.ai:spring-ai-vector-store (Maven): affected from 1.1.0; fixed in 1.1.5

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.
