Detailsinfo

A vulnerability, which was classified as critical, has been found in VMware Spring AI up to 1.0.3/1.1.2. Affected by this issue is an unknown functionality of the component AbstractFilterExpressionConverter. The manipulation with an unknown input leads to a injection vulnerability. Using CWE to declare the problem leads to CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

A JSONPath injection vulnerability in Spring AI's AbstractFilterExpressionConverter allows authenticated users to bypass metadata-based access controls through crafted filter expressions. User-controlled input passed to FilterExpressionBuilder is concatenated into JSONPath queries without proper escaping, enabling attackers to inject arbitrary JSONPath logic and access unauthorized documents. This vulnerability affects applications using vector stores that extend AbstractFilterExpressionConverter for multi-tenant isolation, role-based access control, or document filtering based on metadata. The vulnerability occurs when user-supplied values in filter expressions are not escaped before being inserted into JSONPath queries. Special characters like ", ||, and && are passed through unescaped, allowing injection of arbitrary JSONPath logic that can alter the intended query semantics.

The advisory is available at spring.io. This vulnerability is handled as CVE-2026-22729 since 01/09/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 03/30/2026). This vulnerability is assigned to T1055 by the MITRE ATT&CK project.

The vulnerability scanner Nessus provides a plugin with the ID 304269 (Spring AI 1.0.x < 1.0.4 / 1.1.x < 1.1.3 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 1.0.4 or 1.1.3 eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (304269) and EUVD (EUVD-2026-12795). If you want to get best quality of vulnerability data, you may have to visit VulDB.
