{"cve":"CVE-2024-7885","nvd":{"published":"2024-08-21T14:15:09.500","modified":"2026-10-08T11:16:41.713","status":"Modified","description":"A vulnerability was found in Undertow where the ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes multiple requests on the same HTTP connection. As a result, different requests may share the same StringBuilder instance, potentially leading to information leakage between requests or responses. In some cases, a value from a previous request or response may be erroneously reused, which could lead to unintended data exposure. This issue primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-362"],"references":["https://access.redhat.com/errata/RHSA-2024:11023","https://access.redhat.com/errata/RHSA-2024:6508","https://access.redhat.com/errata/RHSA-2024:6883","https://access.redhat.com/errata/RHSA-2024:7441","https://access.redhat.com/errata/RHSA-2024:7442"],"products":["redhat:build_of_apache_camel_-_hawtio","redhat:build_of_apache_camel_for_spring_boot","redhat:build_of_keycloak","redhat:data_grid","redhat:integration_camel_k","redhat:jboss_enterprise_application_platform","redhat:jboss_fuse","redhat:process_automation","redhat:single_sign-on"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2024-7885","score":0.02644,"percentile":0.85488,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-9623-mqmm-5rcf","url":"https://osv.dev/vulnerability/GHSA-9623-mqmm-5rcf","summary":"Undertow vulnerable to Race Condition","modified":"2026-02-03T03:06:13.966827Z","packages":[{"ecosystem":"Maven","name":"io.undertow:undertow-core","purl":"pkg:maven/io.undertow/undertow-core","ranges":["<2.2.36.Final"],"fixed":["2.2.36.Final"]},{"ecosystem":"Maven","name":"io.undertow:undertow-core","purl":"pkg:maven/io.undertow/undertow-core","ranges":[">=2.3.0.Alpha1 <2.3.17.Final"],"fixed":["2.3.17.Final"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
