Spring AI: Improper Neutralization of Special Elements in Data Query Logic
CVE-2026-47835 is a high-severity improper neutralization of special elements in data query logic vulnerability in Spring AI from Spring, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 1.0.9, 1.1.8 as the first without the flaw, so updating Spring AI to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.3% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Spring AI to 1.0.9 or 1.1.8, whichever matches your release line, or a later version.
- Read the advisory on spring.io for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
