{"id":"GHSA-3pjw-73gf-8qr5","summary":"jackson-databind: @JsonIgnore on a Record property is bypassed with a PropertyNamingStrategy","details":"## Summary\nFor Java Records, `POJOPropertiesCollector._removeUnwantedIgnorals()` records a `@JsonIgnore`-annotated component under its original implicit name before `_renameUsing()` applies the `PropertyNamingStrategy`. After the rename, `_ignoredPropertyNames` still holds only the pre-rename name, so `_ignorableProps` is built from the stale key. The renamed JSON key passes `IgnorePropertiesUtil.shouldIgnore()` and is assigned to the Record's constructor parameter, defeating the `@JsonIgnore`.\n\n## Impact\nA Record using a naming strategy that relies on `@JsonIgnore` to keep an internal/privileged component out of deserialization can have that component set from the wire via its renamed key (e.g. a role/flag controlled by an untrusted client).\n\n## Affected / Patched (verified via `git tag --contains`)\n- 2.15-2.18 line: `\u003e= 2.15.0, \u003c 2.18.8` -\u003e fixed in **2.18.8** (backport `c7c6783`)\n- 2.19-2.21 line: `\u003e= 2.19.0, \u003c 2.21.4` -\u003e fixed in **2.21.4**\n- 3.x line: `\u003e= 3.0.0, \u003c 3.1.4` -\u003e fixed in **3.1.4** (#5974, `baa2cdf`)\n\n## Severity / CWE\nMaintainer: minor. Reporter: Moderate.
