CVE-2026-59888
|
| Summary | jackson-databind: @JsonIgnore on a Record property is bypassed with a PropertyNamingStrategy ## Summary For 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`. ## Impact A 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). ## Affected / Patched (verified via `git tag --contains`) - 2.15-2.18 line: `>= 2.15.0, < 2.18.8` -> fixed in **2.18.8** (backport `c7c6783`) - 2.19-2.21 line: `>= 2.19.0, < 2.21.4` -> fixed in **2.21.4** - 3.x line: `>= 3.0.0, < 3.1.4` -> fixed in **3.1.4** (#5974, `baa2cdf`) ## Severity / CWE Maintainer: minor. Reporter: Moderate. CWE-915; related CWE-345. ## Credits Omkhar Arasaratnam (@omkhar) - finder. |
