Agent-to-controller deserialization filter bypass

Jenkins uses the https://github.com/jenkinsci/remotingRemoting library typically agent.jar or remoting.jar for communication between the controller and agents via serialized Java objects. To protect against deserialization vulnerabilities, Jenkins enforces the https://jenkins.io/jep/200JEP-200...

Security Bulletin: IBM WebSphere Automation is affected by multiple CVEs in the jackson-databind package

Summary IBM WebSphere Automation is affected by multiple CVEs in the jackson-databind package. Vulnerability Details CVEID:CVE-2026-54512 DESCRIPTION: jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.10.0 until 2.18.8,...

jackson-databind: @JsonView bypassed for @JsonUnwrapped container properties on deserialization

Summary UnwrappedPropertyHandler.processUnwrapped replays the buffered JSON for a @JsonUnwrapped property by iterating its properties and calling prop.deserializeAndSet with no prop.visibleInViewctxt.getActiveView guard — the exact guard processUnwrappedCreatorProperties received in the 5971 /...

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...

MiracleLinux 9 : ruby:4.0 (AXSA:2026-1284:01)

The remote MiracleLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2026-1284:01 advisory. ruby/json: Ruby JSON: Denial of Service or Information Disclosure via format string injection CVE-2026-33210 erb: ERB: Arbitrary code execution via...

PYSEC-2026-2530 joserfc: b64=false RFC7797 JWS payloads bypass JWSRegistry payload-size limits during deserialization

RFC7797 b64=false JWS payloads bypass JWSRegistry payload-size limits during deserialization Summary Testing revealed that joserfc accepts oversized RFC7797 b64=false JWS payloads without applying JWSRegistry.maxpayloadlength. The normal JWS compact and flattened JSON paths reject payloads above...

erb: ERB: Arbitrary code execution via deserialization bypass

A flaw was found in ERB, a templating system for Ruby. An attacker who can trigger deserialization of untrusted data in a Ruby application can bypass existing protections. This vulnerability allows for arbitrary code execution by exploiting specific public methods that evaluate template source...

CVE-2026-43866

Summary : CVE-2026-43866 is a deserialization bypass in Apache Camel JMS components. When mapJmsMessage is enabled, camel-jms (and camel-sjms and JMS-family components) deserialize JMS ObjectMessage payloads via ObjectMessage.getObject(). Although a post-deserialization allow-list was added in CV...

jackson-databind has case-insensitive deserialization bypasses per-property @JsonIgnoreProperties

Summary 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...

DEBIAN-CVE-2026-54516

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.21.0 until 2.21.4 and 3.1.4, POJOPropertiesCollector.renameProperties allows a property with @JsonProperty"renamed" on the getter and @JsonIgnore on the setter to be renamed...

CVE-2026-54513 jackson-databind: Array subtype allowlist bypass in BasicPolymorphicTypeValidator (allowIfSubTypeIsArray)

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.10.0 until 2.18.8, 2.21.4, and 3.1.4, BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray allowlists any array type based only on clazz.isArray, without validating th...

CVE-2026-54515 jackson-databind: Case-insensitive deserialization bypasses per-property @JsonIgnoreProperties
