GHSA-3PJW-73GF-8QR5
Vulnerability from github – Published: 2026-07-21 19:33 – Updated: 2026-07-21 19:33Summary
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).

"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\u0027s 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.

"text": "De kwetsbaarheid met CVE-2026-18963 kan een ongeauthenticeerde externe aanvaller in staat stellen om elke gebruikersaccount over te nemen door een wachtwoordreset af te dwingen. Door deze kwetsbaarheid valt het e-mailverificatieproces bij wachtwoordreset te omzeilen en wachtwoorden van gebruikers te wijzigen.\n\nIn Keycloak zijn daarnaast kwetsbaarheden aanwezig in de Fine-Grained Admin Permissions (FGAP) v2, waardoor bepaalde beheerders met beperkte permissies metadata van verborgen groepen kunnen inzien en details van ongeautoriseerde oudergroepen kunnen blootstellen. Verder kunnen geauthenticeerde aanvallers via een legacy client-initiated account-linking endpoint CSRF-bescherming omzeilen en accounts overnemen. Ook kunnen gedelegeerde beheerders met alleen leesrechten client secrets uitlezen door een fout in de secret rotation. Voor OpenTelemetry Java was er een kwetsbaarheid waarbij het ontbreken van limieten op baggage headers leidde tot onbegrensd geheugen- en CPU-gebruik, wat Denial-of-Service kan veroorzaken. Bij Jackson-libraries is een bypass van de @JsonIgnore annotatie in Java Records vastgesteld, waardoor ongewenste toewijzing aan constructorparameters mogelijk is. Ook zijn er bypasses van @JsonIgnoreProperties, ontbrekende view guards op @JsonUnwrapped en ongeautoriseerde schrijfacties op velden met @JsonView. Oracle Database Server\u0027s Fleet Patching and Provisioning component is eveneens getroffen door een kwetsbaarheid die ongeautoriseerde data toegang of Denial-of-Service kan veroorzaken.",

RHSA-2026:54440
Vulnerability from csaf_redhat - Published: 2026-08-12 22:01 - Updated: 2026-08-27 16:00A flaw was found in jackson-databind, a general-purpose data-binding library for Jackson Data Processor. A remote attacker can exploit this vulnerability by sending deeply nested JSON (JavaScript Object Notation) data to a service that reads and processes it. This can lead to a Denial of Service (DoS) by consuming significant system resources, making the service unavailable to legitimate users.

A flaw was found in jackson-databind. This vulnerability allows a remote attacker to bypass the PolymorphicTypeValidator (PTV) when polymorphic typing is enabled and a type identifier contains generic parameters. By crafting a malicious type ID, an attacker can place a denied class as a generic type parameter of an allowed container. This leads to the loading and instantiation of arbitrary classes, potentially resulting in arbitrary code execution.

A flaw was found in jackson-databind. When Java Records use a PropertyNamingStrategy, an attacker can bypass the @JsonIgnore annotation during deserialization. This allows a renamed JSON key to be assigned to a Record constructor parameter, even if it was intended to be ignored. Consequently, an untrusted client could set internal or privileged components from external input, potentially leading to unauthorized modification or disclosure of sensitive data.

A flaw was found in jackson-core. A remote attacker can exploit an incomplete fix in the non-blocking JSON parser by streaming specially crafted JSON data in small chunks. This bypasses the intended number length constraint, causing the parser to accumulate excessive memory per connection. This uncontrolled memory growth can lead to a denial of service (DoS) by exhausting the Java Virtual Machine (JVM) heap.

Vulnerability from osv_ubuntu
jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.15.0 until 2.18.8, 2.21.4, and 3.1.4, Java Records using a PropertyNamingStrategy can bypass @JsonIgnore because POJOPropertiesCollector._removeUnwantedIgnorals() records an ignored component under its original implicit name before _renameUsing() applies the naming strategy, allowing the renamed JSON key to be assigned to the Record constructor parameter. This issue is fixed in versions 2.18.8, 2.21.4, and 3.1.4.
