CVE-2026-14893

Local object-prototype modification via configuration normalization

Published Jul 28, 2026 · Updated Jul 28, 2026

Prototype pollution in IBM Instana Agent builds 1.0.303 through 1.0.320 allows local users to alter object prototypes via tracer configuration. IBM identifies the @instana/core 6.2.1 configuration normalization API as the locus but does not disclose the unsafe key path or normalization operation. Local access without prior privileges or user interaction is required; IBM has not specified the resulting application behavior.
