# CVE-2026-22738: Spring AI: SpEL injection is triggered when a user-supplied value is used as a filter expression key

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 1.1% , percentile 65: FIRST’s model estimates a 1.1% chance of exploitation activity in the next 30 days, higher than 65% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes org.springframework.ai:spring-ai-vector-store (Maven) >= 1.0.0, < 1.0.5, fixed in 1.0.5 ; org.springframework.ai:spring-ai-vector-store (Maven) >= 1.1.0-M1, < 1.1.4, fixed in 1.1.4 . Check your lockfile, including transitive dependencies.

## What it is

In Spring AI, a SpEL injection vulnerability exists in SimpleVectorStore when a user-supplied value is used as a filter expression key. A malicious actor could exploit this to execute arbitrary code. Only applications that use SimpleVectorStore and pass user-supplied input as a filter expression key are affected. This issue affects Spring AI: from 1.0.0 before 1.0.5, from 1.1.0 before 1.1.4.

## Affected packages

- Maven `org.springframework.ai:spring-ai-vector-store` >= 1.0.0, < 1.0.5 → fixed: 1.0.5
- Maven `org.springframework.ai:spring-ai-vector-store` >= 1.1.0-M1, < 1.1.4 → fixed: 1.1.4

## Affected products (CVE record)

- Spring Spring AI: 1.0.0 < 1.0.5, 1.1.0 < 1.1.4

## Severity

- vmware CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.09% probability of exploitation activity in the next 30 days; percentile 65.
