Note that a vulnerability does not need to actually be resolved before it is reported and that these reports can be revised as needed (reopen the issue to request changes). If you do not know how to fill certain fields, mark that in the comment and we will help you. You can delete the comments (or not).--> The Eclipse Foundation is a [Common Vulnerabilities and Exposures](https://cve.mitre.org/) (CVE) Numbering Authority. Creating this ticket initiates **reservation** of a CVE ID for the documented vulnerability. The reserved CVE ID will be posted in a comment below, and kept **confidential** until explicit publication request. > [!note] > > To request CVE _publication_, please open a [CVE publication](https://gitlab.eclipse.org/security/cve-assignment/-/issues/new?issuable_template=CVE%20Publication%20Request&issue%5Bconfidential%5D=true) ticket. Please fill in the fields below to draft the CVE record. --- ## CVE record information **Project name:** Eclipse Vert.x **Project id:** rt.vertx **Versions affected:** \[4.0.0, 4.5.35\] or \[5.0.0, 5.2.2\] **Common Vulnerability Scoring System:** CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H **Summary:** In Eclipse Vert.x versions \[4.0.0, 4.5.35\] or \[5.0.0, 5.2.2\], the `FrameParser` in vertx-stomp creates a `RecordParser` without setting `maxRecordSize`, so any peer that streams bytes continuously without a newline character causes the parser to accumulate data indefinitely. Both the STOMP server and the STOMP client are affected: a malicious server can exploit this against a connecting client, and a malicious client can exploit this against a server before or after authentication. Sustained byte streaming exhausts JVM heap memory, crashing the affected process and causing a complete denial of service. **Links:** - https://github.com/vert-x3/vertx-stomp/security/advisories/GHSA-cchp-hff9-j7q7 **Credits:** Mike Read.
