CVE-2026-109808 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 3.1 (low) and affects SAP Solution Tools Plug-In (ST-PI); no fixed version is listed yet.

## Summary

The SAP Solution Tools Plug-In contains a missing authorization check in a remote-enabled function that lets an attacker with a low-privilege login read data they should not be able to see. The attack can be launched over the network with a login, but the attacker must already know specific internal identifiers to target the function, and the impact is limited to a small loss of confidentiality.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- SAP\_SE SAP Solution Tools Plug-In (ST-PI): ST-PI 2008\_1\_700, 2008\_1\_710, 740, 758

## Description

Due to a missing authorization check in certain remote-enabled functionality, SAP Solution Tools Plug-In allows an authenticated attacker to invoke this functionality to access data that would otherwise be restricted. Exploitation is only possible under certain conditions, as the attacker must have prior knowledge of specific internal identifiers to successfully target the affected functionality. Successful exploitation could allow the attacker to read sensitive information, resulting in a low impact on confidentiality. There is no impact on integrity and availability.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-109808 (Missing Authorisation Check in SAP Solution Tools Plug-In (ST-PI)), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-109808 (entry last updated 2026-11-10):
Affected:
- SAP_SE SAP Solution Tools Plug-In (ST-PI): versions ST-PI 2008_1_700, 2008_1_710, 740, 758
Fixed versions: none listed yet.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-109808 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-109808 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
- https://me.sap.com/notes/3802244
- https://url.sap/sapsecuritypatchday
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
