Description

This security bulletin contains information about 3 vulnerabilities.


1) Improper access control (CVE-ID: CVE-2026-47875)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper enforcement of the trusted-types allowlist in JobParameterDeserializer when deserializing execution contexts from an untrusted data source for the job repository. A remote attacker can supply malicious serialized input to execute arbitrary code.

Exploitation is possible in applications that use Jackson2ExecutionContextStringSerializer.


2) Deserialization of Untrusted Data (CVE-ID: CVE-2026-47878)

CWE-ID: CWE-502 - Deserialization of Untrusted Data

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to unsafe deserialization in DefaultExecutionContextSerializer when deserializing Base64-decoded data with ObjectInputStream.readObject() without a class allowlist. A remote attacker can supply a specially crafted serialized object to execute arbitrary code.

Only the JDBC job repository using this serializer is affected; the MongoDB backend and ResourcelessJobRepository are not affected.


3) Resource exhaustion (CVE-ID: CVE-2026-47881)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in FlatFileItemReader when processing a specially crafted multi-line input file. A remote attacker can supply a specially crafted input file to cause a denial of service.

Only applications using DefaultRecordSeparatorPolicy or JsonRecordSeparatorPolicy are vulnerable; the default SimpleRecordSeparatorPolicy is not affected.
