Check your systems with an agent

Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.

Check whether my systems are affected by CVE-2026-97849 (Apache TomEE: Derby network service listens on all interfaces), 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-2026-97849 (entry last updated 2026-11-10):
Affected:
- Maven package org.apache.openejb:openejb-derbynet: from 4.0.0-beta-1, through 4.7.5
- Maven package org.apache.tomee:openejb-derbynet: from 7.0.0-M1, fixed in 10.0.0-M1; from 10.0.0-M1, fixed in 10.3.0; from 11.0.0-M1, fixed in 11.0.0-M2
Fixed versions: 10.0.0-M1, 10.3.0, 11.0.0-M2.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-97849 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-97849 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Packages (Maven): find every lockfile in each project and run check_stack from the cve.now MCP server on each one. Compare the resolved versions, not the ranges a manifest declares, with the affected versions above. Include transitive dependencies.

Verify against the linked advisories before concluding, and cite the date you read each one:
- https://lists.apache.org/thread/20fl5wnn3slxs0tq0ktmrc9xv9glffhq
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.
