{"id":"CVE-2026-41732","summary":"In Spring for Apache Pulsar, overly broad trusted-package matching in header mapper exposes JDK classes to deserialization","details":"JsonPulsarHeaderMapper matched type headers against trusted packages using a prefix check, meaning that trusting any package implicitly trusted all of its subpackages. Additionally, an empty trusted-packages configuration fell back to trusting all packages rather than applying a safe default allow-list.\n\nAffected versions:\nSpring for Apache Pulsar 2.0.0 through 2.0.5; 1.2.0 through 1.2.17; 1.1.0 through 1.1.17.","aliases":["GHSA-gg69-9wwp-6jx2"],"modified":"2026-08-12T17:56:05.259971245Z","published":"2026-06-09T23:49:31.164Z","database_specific":{"cna_assigner":"vmware","cwe_ids":["CWE-502"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41732.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"2.0.0"},{"fixed":"2.0.5.1"},{"introduced":"1.2.0"},{"fixed":"1.2.17.1"},{"introduced":"1.1.0"},{"fixed":"1.1.18"}]},{"source":"DESCRIPTION","extracted_events":[{"introduced":"2.0.0"},{"fixed":"2.0.5"},{"introduced":"1.2.0"},{"fixed":"1.2.17"},{"introduced":"1.1.0"},{"fixed":"1.1.17"}]}]},"references":[{"type":"WEB","url":"https://spring.io/security/cve-2026-41732"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41732.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41732"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/spring-projects/spring-pulsar","events":[{"introduced":"8d8db89e33bc614efa6024b8706a67f5c3eb04ea"},{"fixed":"14735734a8936c2f0b78a726047f6ad8c8e7fd91"}],"database_specific":{"extracted_events":[{"introduced":"2.0.0"},{"fixed":"2.0.6"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:vmware:spring_for_apache_pulsar:*:*:*:*:*:*:*:*"}}],"versions":["v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.1","v2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41732.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
