# IBM API Connect: server-side request forgery leaks sensitive information to authenticated users

Link for people: https://infrastack.ai/live/CVE-2026-17352 (this .md is for agents)

IBM API Connect V12 OnPrem v12.1.0.0 through v12.1.1.2 has a server-side request forgery flaw (CVSS 8.5). A user with a valid account can make the server send requests and read back sensitive information. IBM fixes it in v12.1.1.3 and lists no workaround.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:API Connect V12 OnPrem affected >= 12.1.0.0, <= 12.1.1.2 fixed 12.1.1.3

## How to check

Check your API Connect V12 OnPrem version. Versions v12.1.0.0 through v12.1.1.2 are affected; v12.1.1.3 contains the fix. IBM lists no workaround. Also check any other API Connect release lines you run, since this bulletin covers only V12 OnPrem; IBM published separate bulletins for 10.0.8.x.
