In versions prior to 3.24.1, 3.20.2, and 3.15.6, there is a potential data leak when duplicating a duplicated context. Quarkus extensively uses the Vert.x duplicated context to implement context propagation. With the new semantic data from one transaction can leak to the data from another transaction. From a Vert.x point of view, this new semantic clarifies the behavior. A significant amount of data is stored in the duplicated context, including request scope, security details, and metadata. Duplicating a duplicated context is rather rare and is only done in a few places. This issue has been patched in version 3.24.1, 3.20.2, and 3.15.6.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","score":6.4},"cwes":["CWE-668"],"references":["https://github.com/quarkusio/quarkus/commit/2b58f59f4bf0bae7d35b1abb585b65f2a66787d1","https://github.com/quarkusio/quarkus/commit/31e8a3bfcf4e223788615d5ce25eb929ca251275","https://github.com/quarkusio/quarkus/commit/d1ee57e7b826872b6355cfec0ae13465840e232c","https://github.com/quarkusio/quarkus/issues/48227","https://github.com/quarkusio/quarkus/pull/48486"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2025-49574","score":0.00283,"percentile":0.20893,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-9623-mj7j-p9v4","url":"https://osv.dev/vulnerability/GHSA-9623-mj7j-p9v4","summary":"Quarkus potentially leaks data when duplicating a duplicated context","modified":"2026-09-10T03:50:25.320184265Z","packages":[{"ecosystem":"Maven","name":"io.quarkus:quarkus-vertx","purl":"pkg:maven/io.quarkus/quarkus-vertx","ranges":["<3.15.6"],"fixed":["3.15.6"]},{"ecosystem":"Maven","name":"io.quarkus:quarkus-vertx","purl":"pkg:maven/io.quarkus/quarkus-vertx","ranges":[">=3.16.0.CR1 <3.20.2"],"fixed":["3.20.2"]},{"ecosystem":"Maven","name":"io.quarkus:quarkus-vertx","purl":"pkg:maven/io.quarkus/quarkus-vertx","ranges":[">=3.21.0.CR1 <3.24.1"],"fixed":["3.24.1"]}]}],"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).
