CVE-2026-41732: CWE-502: Deserialization of Untrusted Data in Spring Spring for Apache Pulsar
CVE-2026-41732 is a high-severity vulnerability in Spring for Apache Pulsar affecting versions 1. 1. 0 through 1. 1. 17, 1. 2. 0 through 1. 2. 17, and 2. 0.
AI Analysis
Technical Summary
The vulnerability CVE-2026-41732 in Spring for Apache Pulsar involves unsafe deserialization due to the JsonPulsarHeaderMapper's method of matching trusted packages by prefix. This approach causes implicit trust of all subpackages under any trusted package. Moreover, an empty trusted-packages configuration does not restrict deserialization but instead trusts all packages by default. This flaw affects versions 1.1.0 through 1.1.17, 1.2.0 through 1.2.17, and 2.0.0 through 2.0.5, potentially allowing attackers to exploit deserialization of untrusted data, leading to confidentiality, integrity, and availability impacts.
Potential Impact
Successful exploitation can lead to full compromise of confidentiality, integrity, and availability of the affected system due to deserialization of untrusted data. This can enable remote attackers to execute arbitrary code or cause denial of service without requiring privileges or user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should avoid using empty trusted-packages configurations and explicitly specify trusted packages to restrict deserialization. Monitor vendor communications for patches or official mitigations.
