Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
When a POST request comes through AJP and the request exceeds the max-post-size limit (maxEntitySize), Undertow's AjpServerRequestConduit implementation closes a connection without sending any response to the client/proxy. This behavior results in that a front-end proxy marking the backend worker (application server) as an error state and not forward requests to the worker for a while. In mod_cluster, this continues until the next STATUS request (10 seconds intervals) from the application server updates the server state. So, in the worst case, it can result in "All workers are in error state" and mod_cluster responds "503 Service Unavailable" for a while (up to 10 seconds). In mod_proxy_balancer, it does not forward requests to the worker until the "retry" timeout passes. However, luckily, mod_proxy_balancer has "forcerecovery" setting (On by default; this parameter can force the immediate recovery of all workers without considering the retry parameter of the workers if all workers of a balancer are in error state.). So, unlike mod_cluster, mod_proxy_balancer does not result in responding "503 Service Unavailable". An attacker could use this behavior to send a malicious request and trigger server errors, resulting in DoS (denial of service). This flaw was fixed in Undertow 2.2.19.Final, Undertow 2.3.0.Alpha2.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-08-01.

Upgrade available Upgrade to 2.2.19 or later
Fixed in 2.2.19
Recommended fix High confidence

Undertow 2.2.19.Final or later (2.3.x series should use 2.3.1+ which contains the fix)

  1. Identify the Undertow version currently in use by checking project dependencies (Maven pom.xml, Gradle build.gradle, or container images)
  2. For projects using Maven, update the Undertow dependency version to 2.2.19.Final or later (e.g., <version>io.undertow:undertow-core:2.2.19.Final</version>)
  3. For projects using Gradle, update implementation 'io.undertow:undertow-core:2.2.19.Final' or later
  4. If using JBoss Fuse 7.0.0, upgrade to a version that includes the fixed Undertow release or apply the JBoss patch
  5. If using Camel K, upgrade the Undertow version in the operator or build the integration with the fixed Undertow version
  6. Rebuild and redeploy the application
  7. Verify the fix by testing AJP POST requests that exceed maxEntitySize - the server should now respond with an error rather than closing the connection silently
Caveat Minor: Undertow 2.2.x to 2.3.x may have API changes; review release notes for any breaking changes in the minor version upgrade
