CVE-2026-14893: CWE-1321 Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') in IBM Observability with Instana (Agent)
IBM Observability with Instana (Agent) versions 1.0.303 through 1.0.320, specifically the IBM Instana Node.js tracer component @instana/core version 6.2.1, contains a prototype pollution vulnerability via its configuration normalization API. This vulnerability allows improper modification of object prototype attributes, which can lead to integrity and availability impacts. The vulnerability has a CVSS score of 7.3, indicating high severity. No official patch or remediation guidance has been provided yet.
AI Analysis
Technical Summary
CVE-2026-14893 is a prototype pollution vulnerability (CWE-1321) affecting IBM Observability with Instana (Agent) builds 1.0.303 through 1.0.320 and the IBM Instana Node.js tracer component @instana/core version 6.2.1. The flaw exists in the configuration normalization API, which improperly controls modification of object prototype attributes. This can allow an attacker with local access to manipulate prototype properties, potentially causing integrity and availability issues within the affected software.
Potential Impact
The vulnerability allows an attacker to perform prototype pollution, which can lead to modification of object prototype attributes. This may result in integrity violations and partial denial of service (availability impact) within the IBM Observability with Instana (Agent) environment. The CVSS vector indicates the attack requires local access (AV:L), low complexity (AC:L), no privileges (PR:N), and no user interaction (UI:N). Confidentiality impact is low, integrity is high, and availability is low.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch links are provided, users should monitor IBM's advisories for updates. Until a fix is available, avoid using affected versions or restrict access to trusted users to minimize risk.
