CVE-2026-15538: Improperly Controlled Modification of Object Prototype Attributes in primefaces primereact
CVE-2026-15538 is a medium severity vulnerability in primefaces primereact up to version 10.9.8. It involves improper control of object prototype attribute modification via the ObjectUtils.mutateFieldData function. The vulnerability can be exploited remotely and affects only unsupported product versions. No official patch or remediation has been provided by the maintainer.
AI Analysis
Technical Summary
This vulnerability in primefaces primereact (versions 10.9.0 through 10.9.8) arises from the ObjectUtils.mutateFieldData function improperly controlling modifications to object prototype attributes when manipulating the Field argument. This flaw allows remote attackers to modify prototype attributes in an unintended manner. The issue was reported early to the project, but no response or fix has been issued. The affected versions are no longer supported by the maintainer, and no patch or official remediation level is available.
Potential Impact
The vulnerability allows remote attackers to improperly modify object prototype attributes, which can lead to unexpected behavior or potential security issues in applications using the affected primereact versions. The CVSS 4.0 base score is 5.3 (medium), indicating a moderate impact with network attack vector, low complexity, and no user interaction required. However, the exact consequences depend on the application context and usage of the vulnerable function.
Mitigation Recommendations
No official fix or patch is currently available as the affected versions are no longer supported by the maintainer. Users should consider upgrading to a supported version if available or applying custom mitigations to avoid using the vulnerable function. Monitor the vendor's channels for any future advisories or patches. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
