CVE-2026-77413

JSONata is a JSON query and transformation language. Prior to 1.8.8 and 2.2.0, the src/functions.js lookup function lacked an Object.prototype.hasOwnProperty check and allowed crafted expressions to access inherited prototype members. An attacker able to supply an expression could use inherited...

JSONata: Arbitrary Code Execution via crafted JSONata expressions

Impact Before JSONata 2.2.0 and 1.8.8 it was possible to execute arbitrary code with crafted expressions, due to a missing hasOwnProperty check in the lookup function: https://github.com/jsonata-js/jsonata/blob/f9632e01e6e67d4f9f00593f9795420cb4b57f48/src/functions.jsL1686-L1705 This was fixed wi...

CVE-2026-44489 Axios: Proxy-Authorization Header Injection via Prototype Pollution — Incomplete Null-Prototype Fix

Axios is a promise based HTTP client for the browser and Node.js. From 1.15.2 to before 1.16.0, nested objects created by utils.merge e.g., config.proxy are still constructed as plain with Object.prototype in their chain. The setProxy function at lib/adapters/http.js:209-223 reads proxy.username,...
