{"id":"CVE-2026-54515","summary":"jackson-databind: Case-insensitive deserialization bypasses per-property @JsonIgnoreProperties","details":"jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.8.0 until 2.18.9, 2.21.5, and 3.1.4, in BeanDeserializerBase.createContextual(), per-property @JsonIgnoreProperties exclusions are applied by _handleByNameInclusion(), producing a contextual deserializer whose BeanPropertyMap has the ignored properties removed. The subsequent per-property case-insensitivity block (triggered by @JsonFormat(ACCEPT_CASE_INSENSITIVE_PROPERTIES)) rebuilds from this._beanProperties (the original, unfiltered map) instead of contextual._beanProperties, then overwrites the filtered map — restoring every property _handleByNameInclusion had just removed. The ignored property becomes writable again. This vulnerability is fixed in 2.18.9, 2.21.5, and 3.1.4.","aliases":["GHSA-5jmj-h7xm-6q6v"],"modified":"2026-07-28T10:14:57.026130903Z","published":"2026-06-23T20:50:25.715Z","related":["CGA-68jj-7999-6x26","SUSE-SU-2026:22504-1","SUSE-SU-2026:2801-1","SUSE-SU-2026:3273-1","openSUSE-SU-2026:11118-1","openSUSE-SU-2026:21201-1","openSUSE-SU-2026:21375-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-915"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54515.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54515.json"},{"type":"ADVISORY","url":"https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-5jmj-h7xm-6q6v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54515"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/issues/5962"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/issues/5964"},{"type":"FIX","url":"https://github.com/FasterXML/jackson-databind/commit/0e1b0b211f7a53baa62ba2f4c9bd006c7bf4d5fa"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/fasterxml/jackson-databind","events":[{"introduced":"81929fad84189ce59ef82e7a6d0df795eb0c7cdb"},{"fixed":"f7b3266eb21a232b35520d31ce5e304beb8f1c7c"},{"introduced":"f644a920f4ac768797edf7709070411837c83ef8"},{"fixed":"09b89813cde3c8a56c696b5b5fb415fa4a1f1d51"},{"introduced":"d51183e4fa171235bcd31c63268c5ad1745afb8c"},{"fixed":"0105ba7c8c7d2aa59707c458eeb6c27e77779734"},{"introduced":"ed2541fedfc6005fd249343f01e6090c8c3395f6"},{"fixed":"0e1b0b211f7a53baa62ba2f4c9bd006c7bf4d5fa"}],"database_specific":{"extracted_events":[{"introduced":"2.8.0"},{"fixed":"2.18.9"},{"introduced":"2.19.0"},{"fixed":"2.21.5"},{"introduced":"3.0.0"},{"fixed":"3.1.4"},{"introduced":"2.22.0"},{"last_affected":"2.22.0"}],"source":["CPE_RANGE","CPE_STRING","REFERENCES"],"cpe":["cpe:2.3:a:fasterxml:jackson-databind:*:*:*:*:*:*:*:*","cpe:2.3:a:fasterxml:jackson-databind:2.22.0:*:*:*:*:*:*:*"]}}],"versions":["2.22.0","jackson-databind-2.21.4","jackson-databind-2.18.8","jackson-databind-3.1.3","jackson-databind-2.21.3","jackson-databind-2.18.7","jackson-databind-3.1.2","jackson-databind-3.1.1","jackson-databind-2.21.2","jackson-databind-3.1.0","jackson-databind-2.21.1","jackson-databind-2.18.6","jackson-databind-3.1.0-rc1","jackson-databind-2.21.0","jackson-databind-2.18.5","jackson-databind-3.0.1","jackson-databind-3.0.0","jackson-databind-2.20.0","jackson-databind-2.20.0-rc1","jackson-databind-2.18.4","jackson-databind-2.19.0","jackson-databind-2.18.3","jackson-databind-2.18.2","jackson-databind-2.18.1","jackson-databind-2.18.0","jackson-databind-2.18.0-rc1","jackson-databind-2.17.0-rc1","jackson-databind-2.16.0","jackson-databind-2.16.0-rc1","jackson-databind-2.15.0","jackson-databind-2.15.0-rc3","jackson-databind-2.15.0-rc2","jackson-databind-2.15.0-rc1","jackson-databind-2.14.0","jackson-databind-2.14.0-rc3","jackson-databind-2.14.0-rc2","jackson-databind-2.14.0-rc1","jackson-databind-2.13.0","jackson-databind-2.13.0-rc2","jackson-databind-2.13.0-rc1","jackson-databind-2.12.1","jackson-databind-2.12.0","jackson-databind-2.12.0-rc2","jackson-databind-2.12.0-rc1","jackson-databind-2.11.0","jackson-databind-2.11.0.rc1","jackson-databind-2.10.0","jackson-databind-2.10.0.pr3","jackson-databind-2.10.0.pr2","jackson-databind-2.10.0.pr1","jackson-databind-2.9.6","jackson-databind-2.9.5","jackson-databind-2.9.4","jackson-databind-2.9.3","jackson-databind-2.9.1","jackson-databind-2.9.0","jackson-databind-2.9.0.pr4","jackson-databind-2.9.0.pr3","jackson-databind-2.9.0.pr2","jackson-databind-2.9.0.pr1","jackson-databind-2.8.2","jackson-databind-2.8.1","jackson-databind-2.8.0"],"database_specific":{"vanir_signatures":[{"signature_version":"v1","source":"https://github.com/fasterxml/jackson-databind/commit/0e1b0b211f7a53baa62ba2f4c9bd006c7bf4d5fa","target":{"file":"src/main/java/tools/jackson/databind/deser/bean/BeanDeserializerBase.java"},"deprecated":false,"digest":{"line_hashes":["62583708381177563534259892150563942610","237429205559261816817740297917107405300","33768538662840574600343674904985860639","145803945554274867026685793446846441723"],"threshold":0.9},"id":"CVE-2026-54515-6449d757","signature_type":"Line"},{"deprecated":false,"digest":{"function_hash":"289270255883554323729001357825114710384","length":2597},"id":"CVE-2026-54515-6eb96247","signature_type":"Function","signature_version":"v1","source":"https://github.com/fasterxml/jackson-databind/commit/0e1b0b211f7a53baa62ba2f4c9bd006c7bf4d5fa","target":{"file":"src/main/java/tools/jackson/databind/deser/bean/BeanDeserializerBase.java","function":"createContextual"}}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54515.json","vanir_signatures_modified":"2026-07-22T20:00:49Z"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
